And with regards to her short naps, I have noticed that she will have some good days when she sleeps well, without any need to extend her naps, and then she will have bad days, when she has very short naps. But after a few bad days she automatically starts having better naps, probably due to all the accumulated tiredness. I guess this is just her rhythm and there is not much I can do about it. She is just very alert and sensitive to her surroundings so she has very light sleep, but when she is tired enough, she sleeps well. Last night there were fireworks in our town and it was really loud, the baby monitor lighted 2 bars out of 5, and lasted at least 30 minutes, but she slept through it without so much as a peep :-)
I cant really leave her by herself in the crib for 20+ minutes, as she starts crying after a few minutes. She doesnt have a mobile over her crib, neither any toys besides a lovie, because that excites her too much and she doesnt sleep
so if I see that really she is not sleepy anymore I will just get her out and try to have a better nap next time as you suggest...
