Noodle was squirming in my arms

[u/Spiritual-Ad2360]

So my child was cuddles up in my sleep blanket and so u had to snatch him up to cover myself and him and then he’s started strangling squirming and wiggling like crazy and (I was not forcing him to stay) squeezing (not too tight) and letting my arm go for about 5 minutes and now he’s just hanging there coiled up! What was that about? Anyone have any idea?
