Thank you for getting back to me.
She's just about to turn 4 months and is a proper boobie monster. Although she's a big girl, her legs aren't chunky so when she wriggles a bit too much they leak
I did find that if her vest was slightly tight that would cause leaks.
The Mio Softs are 100% cotton. I think I may have to dig them out of the wardrobe and see how they cope.
I wish I had known more about the microfibre. I stocked up on them whilst I was pregnant. Looks like I should have stocked up on the bamboo ones instead. Have you had any experience with charcoal inserts?
I really struggle to find any advice online about reusables. Everyone seems too reliant on disposables. Even the Drs, nurses and midwives seem shocked I use them.
