S.H.
I did what Dori W. did, with both my kids, whom I breastfed.
A child, will naturally sleep for longer stretches the older they get. I never 'sleep trained' my kids. I went by their cues.. and per our Pediatrician who echoed the same thing.
And I ALWAYS knew, when my kids were having growth-spurts... per their increased hunger and intake and sleeping.
Whether she needs the 'nutrition' or not is not the point. If a baby is hungry, they are hungry. Their stomach is empty. That has nothing to do with if they need the nutrition... their body has metabolized their food, already.
sleeping for 8 hours, is a LONG time, for a baby.
Personally, MANY Adults, don't even sleep for that long of a stretch, either.
I don't. Even if I am tired.
If I am hungry, *I* wake too...
Appetites fluctuates... in any person, baby or adult.
My kids, did not sleep ALL night... until they were about 2 years old. Naturally.
all the best,
Susan
