4 week old DS with terrible stinky wet farts!

[BigMommaOfAlmost4]

DS has not been a regular pooer since birth. It took him almost a week to do a proper one after birth and since then he goes every 2/3 days and when he starts it is neverending and a very large amount!

In between this he does a lot of very stinky farts and has skidmarks in his nappy. I am having to cover him in Sudocrem as he is getting a bit sore. Now I normally find baby farts quite cute but his are quite offensive and fill the room!

He is having both breast and formula. He will not take a full feed from the breast as I had to stop feeding him when my nipples got so sore I was in agony and bleeding, since then he prefers the bottle but will take take snacks from me . He is on C&G formula. We have tried a few different formulas as he was sicking up a lot but has completely stopped now he is settled on that one.

HV is not worried about the time in between poos and he is not constipated so any ideas on how we can relieve him of his constant farting??

Should say I stopped bf to give my nipples time to heal (2 days) and DS was refusing to go back on the breast but after constant offering will now go on in between feeds, not when really hungry though as he obviously finds the bottle easier!

Will post in breast and bottle section as well.
