Quoting ~mama~:" My DD is 6 weeks old and since she was born I have been waking her up at night every 3 hours to feed/change her. Is it too early to let her sleep and miss a feeding? "
DS has normally woken up every 3-4 hours by himself since he was born...I've never woken him up to feed him. He's now to the point where he'll go between 5-6.5 hours once a night. He's almost 10 weeks. I'm sure it's fine to let her sleep
It hasn't bothered DS and he's still on track for weight gain.
