3 month old constipated

Marisa • Momma to Rowan Maverick born 10-5-16 & Rhen Mason 11-28-18 💙

He is formula fed and has been on the same formula basically since the beginning. Not sure why he’s so constipated! He has not pooped a soft poop in about 5 days! Two days ago he had a really hard poop but it wasn’t much at all. He’s been super unusually fussy and i think that the pooping has got to be the problem! I called his doctors office today and a nurse was suppose to call me back with what the doctor said but they never did and I forgot to call back before they closed because I’m so scatterbrained 🤦🏽‍♀️
