5 month sleep issues!

Al

My son was sleeping through the night usually 9-12 hours since a little before 3 months old. He will be 5 months old in a few days and now hes been waking up twice around 2am and 5am. And he cries and screams like he’s a newborn again so I always feed him or else he won’t stop 🤦🏼‍♀️.

Anyone else have this happen? He was doing great for like 2 months straight. Now this :/
