I'm at a lost

I had my son on June 17 and he was breastfeed first 2 day but it didn't work out his lips was to small and I didn't have enough fat in my milk well they gave him enfamil yellow can I had that for a few weeks will it wasn't agreeing with him so I switched to the gentlease one and been on it since but it still seems like it don't agree with him he don't poop for least 2 days and seems like in pain he always crying or screaming I have to give him gripe water to help him he not sleeping when he does it 15 mins here and there and if he in good mood it about 1hr I tried talking to his doc and he said it normal im moving in 5 days to new state and it gonna take time to get a new doc there but idk what to do in mean time and in driving to the new state that takes 2 days and I have a 8 and 5 year old to he seems in pain and advice my mom wants to keep him on the gentlease till we get there but my husband wants to try the yellow can again since he 1 month old now
