Constipation remedies?

Bryna

My sweetie girl is having a hard time pooping lately. I’ve had to help her almost every time and she cries and cries and they’ve been a thick paste. She’s exclusively breastfed and I just started her on iron drops which the pharmacist said can constipate her so I’ve cut down on them a little. Ive read that I can give her apple or prune juice but I’m just not sure about that. She just seems so little still! She’s 4 1/2 mo right now. Hellllppppp!
