I keep hearing newborns shouldn't go more than 4 hours without a feed. I know some mums choose to let their little ones sleep right through if they don't wake themselves and I'm not judging that choice at all. I've been trying to follow it, mostly because ive heard they can get dehydrated which worried me, it's usually no issue as my baby wakes me well before this, however at 7 weeks on at least 2 occasions recently I think I may have let him go more than this due to not setting an alarm properly (or accidentally turning it off and not getting up), and him not waking me. I then felt terrible, in fact on one occasion I thought he slept through a feed but being so tired I couldn't really remember. Who else does this, and how long for? I know his stomach will be rapidly increasing in size and he'll be able to hold more too, so at what point can he go longer if he doesn't wake up naturally?
