Help! 3 month old sleep problems

Janice

So my 3 month old started this new thing. He wakes up randomly through the night and just wants to be picked up. He’ll fuss and cry and the second I pick him up he cuddles and goes right back to sleep. Any ideas on how to stop this? It’s happening so often that I’m tired all the time now. He’s not my only child so it’s hard being so sleep deprived
