Period swimwear for holiday

[Bakedbeansandtoast]

Can anyone recommend period swimwear for DD13? I think she'll be due when we are supposed to be abroad and I don't want it to ruin our holiday. Bonus points if they are suitable for heavier days - I've found lots of options online but wondered if anyone had any tried and tested recommendations. She's tall for her age so would easily fit adult recommendations. TIA!

I have used the mobi body adult size bikini bottom for centre parcs used throughout my period. I actually wore them underneath my swim suit. Spent an hour a day in the pool and it was completely fine even down slides etc. I would recommend. Not sure how they would cope for longer times I suppose it depends on the flow. I am a medium flow I would say if that helps

As somebody who has awful awful periods (change tampon every hour) I wear a tampon and have great ones from Mobibody that help me feel less paranoid x
