My LO has been sleeping through the night since he was 2 months old and he's turning 4 mth next week. I still wake him up to feed despite him sleeping soundly as I thought babies should still be fed at night even though we can drag the interval to 4/5hours instead of 3hours. What are your thoughts about this? Shall I stop this routine if my LO is sleeping through the night and only feeds him after he is awake? eg, sleeping from 10pm to 6am
