DS is 5 months and for the past week or so, seems very disinterested in eating. We used to have 6 to 7 feedings a day, about 5 - 10 minutes each. But now he is eating about 4 times a day, at most 6 minutes each, and then the other 2 times he'd barely swallow 10 times before he is done. Just wondering if that's normal. He does seem to have less dirty/wet diapers, but not significantly less.
