How to get 15 week to sleep during the day

Hilly

Hi ladies,

I have a 15 week old baby who’s not the greatest daytime sleeper. Yesterday, he slept for no more than 15 minutes and wakes up shortly after he’s put in the crib. Today, he’s had about 4 short naps (longest is 20 min) and it’s still not enough because he’s tired and cranky. I’ve tried to keep up with early cues of sleepiness and nurse or rock him to sleep but neither seems to work. At times he’s soo sleepy but will not sleep. Please help!
