PUPD help needed - how long do you give it per session?

[NoisyBrain]

I'm trying to get my 6 month old DS to go off to sleep by himself, starting today with naps. Up til now he's been mostly rocked to sleep, or fed to sleep during the night. After an unsuccessful attempt at PUPD this morning where I gave up after about an hour, he ended up having a 10-minute catnap after a feed, then falling asleep in the pushchair while we were out and sleeping for an hour and 10 minutes.

I put him down for a nap again about 40 minutes ago. I'd held him til he was drowsy but not quite asleep. As soon as I laid him down he woke up. He wasn't upset so I left the room. At first he was 'singing' to himself and playing, then started crying. I picked him up and held him til he stopped crying, put him down and left the room. He's just started again. Do I really just keep going til he goes to sleep? What if he just doesn't?? How long do I try before admitting it's not working? This morning I ended up feeding him because he'd been awake so long he was overdue a feed. I can see the same thing happening now, or it getting too near bedtime for a nap and ending up with a very overtired baby. It's only the first day and I feel like giving up already

I gave up after an hour again. It ended up turning into a combination of PUPD and CC, with DS just getting more and more upset. In the end I BFd him as it was the only thing that would calm him down and he fell asleep.

So that's nice work all round today. I've made my baby hysterical twice and replaced one prop (rocking to sleep) with another (feeding) on both occasions.

I suppose my question still stands. If I were to do PUPD properly, how long should I persist for at first?

Hi noisy no advice on timings (can't recall them, have blocked out hideous recollections!) but I think the forums at the baby whisperer site are quite useful. In saying that PUPD drives my 6 month ds absolutely round the twist, he just hates it!

I carried on until they went to sleep, however mine were much younger so I think it was properly easier for them ~IYSWIM
