2 week old constipation

Allison

Soooo what should I do? My son haven’t really pooped besides balls since he’s been born. I thought maybe formula because the similar advanced made both older kiddos constipated so put him on sinsitive and same situation talked to pedi about it and gave us 5 days then try total comfort but apparently it’s hard to find in stores. Anyone else have this issue? Is so what did you do or formula did you try?
