I hate this! With DS, it's anywhere between 30-45 minutes. I can put him down and know, within a 15 minute window, when he will start stirring and wake himself up.
Does this ever end? Do they grow out of this at some point? I'm hoping there will be a day where I can put him down and not tune in to the video monitor 30 minutes later waiting to go help him stay asleep or back to sleep.
Re: 45 minute intruder
He cries. It starts as squirming, then fussing then crying (all within 3 minutes).
He can put himself to sleep for his naps but he can't put himself back to sleep after waking. He's definitely not ready to be awake either.
Here here!! This is us to a T... supposedly they grow out of it... well of course they have to at some point, at least by the time they are in school lol. My friend's DD grew out of it around 3.5-4 months so I was hopeful, but alas, we are still going strong!
We'll miss you sweet Debbie Girl (4.21.12) and sweet Cindy Girl (8.9.12)

So do you put your DS back down or is the nap usually over then?
Our son did this at night...EVERY night for 2 months...ugh. Everyone said he was overtired or overstimulated before bed, but he never did it for naps and we tried everything to kick it. At almost 4 months, it suddenly stopped. He still takes occasional naps that are only 45 minutes, but he has at least 2 a day that are 1-2 hours in length. And for 10 days straight, he's made it 4 hours to his first feeding (no 45 minute intruder there!)
I hope it stays away, I hated that bastard!
It was happening for nighttime sleep?? ew.
Love your little guy's name!! (My son is Cameron too)
There is hope!! Yay!!
Yes, every night -- it was misery in our house :c( Love your little guys name too :c)
So is this just a phase?? DD took GREAT naps during the day up until this week. Usually 4 naps a day, at least 1 hour with one always being over 2. This week I'm lucky to get to 45 minutes. No fun!
This - we still have these and DD takes 4-6 per day. It is a lot of napping and getting her to nap but less stressful that trying to get her to sleep longer. Pedi says she will likely grow out of it in next couple months.
It depends... sometimes he seems happy enough, so I get him up, if he still seems sleepy or if I think I have half a chance (i.e. he is not kicking his legs like crazy or going nuts) then I try to put him back down. I usually don't have much luck - sometimes I get 10 more minutes, sometimes I get 1/2 hour more. But usually we have 5 - 45 minute naps a day.
Same story. DD goes down by herself, but we use her nuk to help her get past the 45 minute intruder. I read somewhere that at this age babies are often not capable of getting themselves back to sleep very well without some help. I'm okay with it, as DD is able to get herself to sleep initially. We rarely have this problem at night, only naptimes. I always try to get longer naps out of her (by putting in her nuk) but if she's still awake after about 15-20 minutes, I consider naptime to be over and get her up.
