My little boy is 3 weeks and 6 days now, and it was impossible swaddling him since first week. No matter how well the swaddling was done, he can always wriggle his way out of it. By 2nd week, we would find him sleeping in a different spot of the cot from his wriggling.
I find it super cute but of course checking on him more frequently so I can shift him
back to the center of the cot.
Any of your little one a strong wriggler too?
