Okay gross question: DSJUST moved to size 5 diapers - like we were using them at night and were trying to finish up the size 4s because he technically still met the weight requirements. Anyways, in the last week or so he's had a massive growth spurt and is eating like a horse, especially in the afternoon/evening and drinking a ton of milk and water. The problem is he doesn't poop before bed. He's remarkably STTN and everything but when he wakes up his diaper is overflowing with pee and a massive BM, soaking through his pajamas and the inside of his sleep sack. And more often than not we have to change his sheets too. Like the diaper is legit 5 pounds and falling off him! We use Pampers Cruisers - do you think an overnight diaper would help for BMs? Or should we move to size 6 diapers? Or should we just deal until the growth spurt is over since he's sleeping through? I've heard of heavy wetting but heavy night pooping is a new one!
