My BS is just 4 wks old but is becoming increasingly fussy before daytime naps. When I spot signs of tiredness I put him in his crib and he immediately cries/fusses/kicks/pulls at ears etc. I read this is a sign of overtiredness, but he just won' t drop off. When he does, it's with a dummy and usually only for a max of about 5 mins before he wakes anf the whole cycle starts again. He constantly drops his dummy too, but he's not spitting it out - he seems to be desperately reaching for it. If I pick him up, he falls straight to sleep, but wakes again if I put him into his crib. What's going on? Am I worried about nothing? Is he just too little to go to bed on his own?
