Especially if you are breast feeding it is totally normal to go 5 days. Let nature do its course!
No need to give you baby anything hair yet. BF babies sometimes don't poop often. My BF daughter once went 1 week without going and dr said it was ok. She was 8 weeks
I did the clear Karo syrup and it work.
I give my 4 week old kairo syrup or baking soda. They both work. And sometimes I just give him an ounce of nursery water.
My 2 week old was constipated but everybody kept telling me it was normal. Anyway, he's breastfeeding and getting a little supplement also, but he was showing no discomfort. Yesterday he finally pooped twice and once today. My pediatrician said breast milk just doesn't sit in the belly long.
