Everyone at work keeps asking me if my son (9 months) is sleeping through the night. When I tell them he still gets up 1-2 times/night to nurse, they act as if that is ridiculous and make suggestions, like giving him formula before bed, or letting him cry, etc. Are all the other 9 month babies sleeping through? Is it wrong to still nurse him at night? Should I be doing some sleep training? I'm a little confused about this whole thing.
