Thank you for th reply!
Yes, he sleeps less than he should during the day. And that happens because sometimes, with my little one and all the duties and don't have the time needed to make him sleep and put him on the crib... And when I do that, most of the times he wakes up right after I put him in the crib swaddled. He sleeps very well with me, but not in his crib during the day, vir at night he sleeps weel on his crib. I don't know if he is sensible to the noises of the day, or if I'm not taking the time needed for him to really sleep before putting him down.
And I almost never sleep during the day, because when ones sleeps the other is up or Something comes up to be done, so sleeping during the day is a hard task for me!"
I'm gonna read the link you sent! Thank you so much!
