DS is fed pumped milk via bottle and has done well with it - he's 11w and has been exclusively bottle fed since 6w when we had breastfeeding problems. The past 3 days though it is a struggle to get him to drink all of his milk during the day. At night, he takes his 3.5-4 oz just fine (he's 11w but a peanut) but during the day he stops 1/2 way through and then acts like I'm trying to gag him. Eventually after fighting me he will take it - he dibs and dabbles over an hour and usually I get him the rest of the bottle when he goes down for his nap (swaddled), so he is taking the same quantity. He otherwise is acting normal.

Anyone experience something like this? Tips?
