DS is 13 weeks old and always wakes between 3 and 4 am for what we think is a feed but in reallity he doesn't take that much. He'll take half a feed of 3 oz as he's usually on 6 oz per feed.
Without letting him get upset and scream the place down what's the best way to find out if he is waking through habit or is a bit hungry? At 11 pm he will usually take a full feed but at some feeds during the day he won't take a full feed at all and leave some.
Any thoughts.
