Why won’t my son sleep?!

Ki

Literally nothing has changed, but the past week my son has been fighting bedtime. I did the normal routine tonight twice. But still wouldn’t go down. Then I just held him, and even though he’s falling asleep in my arms, he still won’t sleep in his crib. I have him Tyleno about a half hour ago. But he’s just standing in his crib crying bloody murder. Thinking of just letting him cio but my husband needs sleep because he’s waking up really early.

Ugh, any one know why he’s doing this recently?
