A Dad’s Guide to First Periods
Be prepared. Stay calm. Help her feel confident.
Your daughter’s first period can feel like a big moment for her and for you.
You may be wondering what to say, what to buy, how to support her, or how to make sure she does not feel embarrassed. The good news is this: you do not need to know everything. You just need to be calm, prepared, and willing to help.
At Liberty Underwear, we believe periods should never feel shameful, scary, or difficult to talk about. Our reusable period underwear is designed to help girls, teens, and adults feel protected, comfortable, and confident at school, at home, overnight, on holiday, and every day in between.
If your daughter has just started her period
First, take a breath.
This is normal. She may feel embarrassed, emotional, confused, proud, worried, or all of those things at once. Your response matters.
What to say
Try something simple and calm:
“Okay, don’t worry. This is completely normal. I’ve got you.”
Or:
“Thank you for telling me. Let’s get you what you need.”
Or:
“You’re not in trouble. There’s nothing to be embarrassed about.”
The aim is not to give a perfect speech. The aim is to make her feel safe, supported, and not ashamed.
What should a dad buy for his daughter’s first period?
A simple first period kit can make a huge difference. It gives her confidence and helps her feel prepared, especially at school.
First Period Kit Checklist
We recommend:
-
2–3 pairs of period underwear
-
A spare pair of ordinary underwear
-
A waterproof storage bag
-
A small discreet pouch for her school bag
-
Wipes or tissues
-
A spare pair of leggings or tights if she wants them
-
A simple care card explaining how to rinse, wash, and reuse period pants
Period pants are especially helpful for first periods because cycles can be unpredictable. Your daughter may not know when her period is coming, how heavy it will be, or how often she needs to change. Period underwear gives her an extra layer of reassurance.
Why period pants are a good choice for first periods
Period pants look and feel like normal underwear, but they include absorbent layers to help protect against leaks.
They can be worn:
-
On their own, depending on flow and absorbency
-
As backup with pads or tampons
-
Overnight
-
At school
-
During sports or everyday activities
-
For extra confidence when periods are irregular
For many girls, period underwear feels less intimidating than learning pads, tampons, or menstrual cups straight away.
Liberty period pants help her feel:
-
Protected
-
Comfortable
-
Less worried about leaks
-
More confident at school
-
Prepared for unexpected periods
-
In control of her routine
What if she starts her period at school?
This is one of the biggest worries for both daughters and dads.
A school period kit helps her handle the situation quietly and confidently.
What to pack in her school bag
-
One pair of period pants
-
Waterproof storage bag
-
Small pouch
-
Spare underwear
-
Wipes or tissues
-
A short note reminding her what to do
You can say:
“If it happens at school, you have everything you need in your bag. You can go to the toilet, change, and put anything used into the waterproof bag. Then we’ll sort it at home.”
This kind of preparation helps reduce fear and embarrassment.

How do period pants work?
Liberty period underwear has absorbent layers built into the gusset area. These layers help absorb fluid, protect clothing, and keep your daughter feeling dry and secure.
After wearing, she can rinse them in cold water, wash them according to the care instructions, dry and reuse them.
Simple. Comfortable. Reusable.
What absorbency should I choose?
If this is her first period and you are unsure, start with protection that gives her confidence.
Good options for first periods
-
Medium absorbency for lighter days
-
Heavy absorbency for school days or longer wear
-
Overnight protection for sleeping
-
Multipacks so she has enough pairs for a full cycle
If she is worried about leaks, choose a higher absorbency to begin with. Confidence matters.

How should dads talk about periods?
Keep it normal. Keep it kind. Keep it short.
You do not need to make it a big emotional event unless she wants to talk. Some girls want information. Some want privacy. Some want reassurance. Some just want you to buy the right products and not make it awkward.
Helpful things to say
-
“This is normal.”
-
“You can always tell me if you need supplies.”
-
“I’ll make sure there are period pants and products at home.”
-
“You don’t need to feel embarrassed.”
-
“Would you like to talk to me, or would you prefer to speak to someone else too?”
Avoid saying
-
“You’re a woman now.”
-
“Why didn’t you tell me sooner?”
-
“This is awkward.”
-
“Let me tell everyone.”
-
“Are you sure?”
The best thing you can do is show her that periods are a normal part of life.
Should I ask a woman to help?
You can offer your daughter the option of speaking to her mum, auntie, older sister, family friend, or another trusted woman.
But do not disappear from the conversation.
She should know that you are also safe to talk to, happy to buy what she needs, and not embarrassed by periods.
You can say:
“I’m always here to help, and I can also ask someone you trust if you’d like more advice.”
That gives her choice without making periods feel like something dads cannot handle.
When should I seek medical advice?
Most first periods are normal, but if you are worried, speak to a GP or healthcare professional.
Consider getting advice if:
-
She starts bleeding very young
-
Her pain is severe
-
Bleeding is extremely heavy
-
She feels faint or very unwell
-
Periods are causing major anxiety
-
You are unsure whether symptoms are normal
This guide is here to help with preparation and confidence, but medical concerns should always be discussed with a professional.
Ready to help her feel prepared?
You do not have to get everything perfect.
You just have to make sure she knows:
She is safe.
She is normal.
She is supported.
She has what she needs.
Liberty period underwear helps make first periods easier, calmer, and more comfortable for daughters and gives dads a simple way to be prepared.
