🚨TMI BABY POOP 🚨normal??

My little boy is 15 weeks on Monday. He has recently started Neocate for his top ups (2 two ounce bottles a day)for a suspected dairy allergy, I’ve eliminated dairy from my diet and he’s just started gaviscon for silent reflux.

He still seems to be a bit uncomfortable and wanting to be upright but apart from that he’s completely fine.

He’s just done his first poo in 4 days... I’ve never experienced poo like this it’s usually runny/watery/mucousy. There is a small amount of mucous in it but barely noticeable.

Is this a normal poo?
