so its my sons second day at day care he's two months on the first day she gave him all formula as my stupid self forgot my milk sense then he won't take a bottle from her today even when its breast milk he only took and ounce the 6ish hours I was gone he doesn't eat as often as normal when home with him I haven't changed his diaper sense we've been home which we got home at 4 he peed a very tiny bit not anything that would make one change a diaper and he hasn't pooped sense hell monday morning before his first day I'm sure he poops there but I know my son he poops all day multiple times a day and he hasn't when he woke up this morning I didn't even need to change him that's not normal for him....I'm starting to think daycare is have a negative affect on him or is this normal? I have 8 months i need to finish and if he's not going to eat at daycare...how could I continue.... is this normal or is it because the formula he had all day the first day
