E. D,
I am a mom of 3- 8 months, 2 1/2 years, and 4 1/2 years. All girls. I know that boys are different than girls when it comes to sleep. There are so many aspects to naptime. Personality, consistency, and routine. I know that you have tried lots of things, the thing is you have to keep doing the same things for it seems like a long time. At 10 months old your baby should be taking 2 naps 1 1/2-2 hours each nap. a morning nap and an afternoon nap. First look at your babies nighttime sleep-is that consistent? Same bedtime routine? Same bedtime? Also, they are extremely smart-my first knew at that young age that she was "missing out" and tried her hardest many naptimes to stay awake no matter how tired she was. When I was consistant and left her in her crib to play for at least an hour-she realized that was nap time. (she did not cry during this time-was mad and would cry-yell for the first 10 minutes sometimes-but i would just tell her she needs a nap time). Put down at the same time every day (I do 9:00/9:30 and 1:00). Try and not skip the naps. Be at home and make this a priority. If you are going out 2 or three times a week during these times, this is not consistent and your baby will not be in a routine. Have the room quiet and low light. I use a fan for my 8 month old because she is such a light sleeper. Teething affects her greatly-she does not nap when she is teething-she just won't. I keep laying her down at the same time though. Also watch your diet. Are you nursing and drinking coffee? Caffeine? Lots of sugar? I also put a few soft dolls/toys in the crib so my daughter can play with them to calm herself down. Did your son learn how to fall asleep on his own-or does he not know that skill? (they learn how to do this on their own-if you rock them, or help them fall asleep for every nap/bedtime, they will not know how to do this by themselves). I hope this was helpful. Also, do a routine. Say night night time, change diaper, read a short book, then gently lay down with blankie, kiss and say goodnight. Leave him. If he doesn't go to sleep and is happy-leave him for up to an hour or hour and a half. If he is mad, keep going in and tell him its nap time, he needs to sleep. Be consistent. YOu are the parent, he doesn't know what he needs. You do.
