MF squishes if it gets sat on etc, and squeezes the liquid out. I often use a little MF 'booster' (A cut up MF towel lol) in Dawns wet zone, just to get a bit more... umph!
Today, have sent her with a BG in her bag for nursery with a hemp booster on the bottom, then the BG one, then a bamboo one on the top. Hemp is slowler to absorb than Bamboo or MF so it's best on the bottom. The BG one is only left in there because she's gone through a super wetter stage of out peeing all her pockets which are normally fine for a couple of hours
We normally use YoYoo which are bamboo pockets, boosted with an extra LL bamboo booster and they'll last us 2 hours minimum. The other day I, for some reason, put 4 nappies in my bag. I'm glad I did as she out peed them all to the point where I had to let her run around bare bummed at Nanas house before we went home, for fear that she'd out pee the last nappy I had left and we'd have no nappies for the car trip home
