Anyone else?

My son has gotten SUPER clingy lately. Every time I put him down for nap or bedtime he says "mommy cuddle, mommy cuddle." And often won't nap if I don't lay down with him. We overnight sleep trained him at 9.5m and he hasn't slept in bed with me since. We've tried a few times while traveling and he won't sleep, but the past week or 2 he's fallen asleep in my arms a few times. He woke up at 5:00 this morning screaming for mommy cuddles and wouldn't go back to sleep in his room.
