Why Is My 1-Year-old Refusing to Go down for Naps and Bedtime?

Since age one my son (now 19 months) has woken between 6:30 and 7:30 naps at 11:30 until 1:00 or 2:00 and goes to bed at 7 pm. He used to have a nuk but now does not. He did the same thing with throwing everything out of the crib. I would have to go up a few times and give them back (he has a stuffed monkey) I think part of it was to see what would happen, then he realized he couldn't get his lovey back on his own. Since we gave up the nuk my son sleeps better( i have only had to go to his room once in the last 2 months after he has been asleep because he had a bad dream). we put a radio in his room to help him relax. When my son used nuks we left 3 in the crib with him so he could try to get them. then i kept some on his dresser so when i went in i could grab one and pop it in his mouth to save time on searching. i gathered them up every night before bed. Good luck! my son ditched the 2 naps at 11 months. maybe if you got down to one nap it would help him rest better but i don't know your child directly so if one nap means extra cranky then stick with the 2 :) it is so hard because every child is different

We are going through the same thing, including the sharing a room with an older sib thing. Right now the cause-and-effect realization is very strong, and he is learning what he has the power to do. He throws loveys out, mom or dad comes in to return them, and he gets both entertainment and another security check by seeing Mom or Dad. He also is developing more socially and does want to keep playing with his brother.
We gave our daughter the option of laying in our bed to fall asleep if her brother was keeping her awake, either with crying when I left the room, or chatting away. I'm not sure if this was a great idea, because it often caused chaos with her running back and forth between rooms and ultimately keeping my son awake longer (though he usually gives up quickly and goes to sleep if he is the only one in the room). Now, she is used to his chattering and if she is tired enough, she will just fall asleep with him making noise. Its like the grandfather clock chime that you don't even hear anymore if it is a regular occurrence!
As for the naptime issue, although your son is just turning one, his internal schedule may be dictating that one long nap will work best for him. I'd advise against the on-and-off in bed thing, because kids sleep MUCH better with predictable schedules. It helped for my son to feel he was part of the bedtime/naptime routine. He turns out the light, and pushes the button on his music box before I lay him in bed. Whatever is safe for him to contribute to in his bedtime routine, let him participate.
My guess is that he is just really excited about practicing new "skills" he has picked up, and when the novelty wears off or his little body is just too tired, whichever comes first, he will go back to a good sleeping routine again.

i think its the ferber method that does this to some kids. it just doesnt jive for some kids, they get confused because they dont know how to tell time so they dont know when or if you are going to come back. throwing stuff out guarantees you will have to come back because he screams until you do. this also teaches him the level he has to get to in order for you to respond, so he will start using that level of screaming first instead of after a while, you know? if the quiet cries dont get a response, then a flat out scream will, and he will start skipping the quiet cries.
its not always in best interests of everyone to skip those responding to those quiet cries!

and its not unfortunate that hes hooked on his nuk, or a snuggly item. these things comfort kids, and they are important to any self reliance. if you are absent, these things provide comfort. dont stress about them until your dentist or family doctor starts worrying about teeth issues because of the nuk.

teething molars could have a lot to do with it. at the same time my son was teething, i had wisdom teeth pain and im telling you, it hurts more than you think. he might need some extra time just with you holding him or snuggling him and comforting him. its OK for our kids to need us. they cant be confident and independent unless they are allowed to be able to rely on us for a while. let him need you. this time is so quick, and if he can trust you now to be connected to him, then he will be setting up trust for when hes older, you know?

now that im reading the last bit there; it is VERY possible that hes done with 2 naps. hes about the right age, but hes also acting wierd. so chances are he can quit 2 naps and go down for nap the same time as siblings (after lunch?). that should help him i would think. it could be that the WHOLE issue is because he doesnt need both those naps.

if you switch to 1 nap, and he seems worse, try to switch back, or try his nap an hour earlier, and he might need to go to bed earlier. but just try your hardest to find that connection, and listen to your instincts. that is most important; not what we think, not what doctors or family thinks, but what YOU feel you need to do. :)

Go to one nap - life will be easier and he sounds ready. My daughter stopped sleeping during her morning nap a week before she turned one. On her first birthday she only took one nap and has ever since. She's a great sleeper and sleeps 12-13 hours at night and a 2 hour nap every day because of it.

It sounds like your son is ready for one nap instead of two. At one year-old, this would be common.
