valentin use to drink 17-19oz a day and i never figure how he still managed to be on the 50 percentile.lol. The last week he has taken 28-30oz a day. Today he has been very sleepy and only taken 15oz, half a jar of baby food (it was his first time eating baby food) and its 8pm here. Its my second baby but my first time formula feeding so im at a lost. Should i let him sleep? i dont want him to lose his chubyness.lol.
