Nap or no?

Cindy

If your baby wakes from a nap, eats, and starts yawning several times shortly afterwards, do you keep them up or lay them back down? My little one is 4 months and I feel kinda guilty putting him back down if he fusses but I also feel like if he’s still tired, I need to let him get his rest. Idk what the right thing is, though. He sleeps well at night, waking a few times to nurse. What do you guys do?
