Apple juice for constipation?

Kayla • 10/13/2019 💙👶🏻

My son is 3 1/2 months old and has not pooped in 3 days. He is super gassy and uncomfortable all day and is constantly straining to poop. I’ve been using gas drops and using the windi on him and nothing seems to be working. Is it safe for me to give him apple juice to try and relieve his pain?
