Hi, the only rules for my little one is just to aim for no more than 2 hours between napping and to have a 6-6.30 bed time.
Until now he would have screamed his head off the second he was put in the cot, but as long as he goes down before it's too late (like I say - my particular problem here was terrible over-tiredness) then he will settle and hasn't cried once yet.
Someone asked how exactly I settle him? I lay him down, use a dummy and (depending how close to sleep he is) I do the following:
Play a very gentle and whispery game with a teddy
Read a book
(but normally he seems ready for me to just move straight on to..)
Stroke from crown down to the end of his nose gently and slowly over and over whilst slowly saying my keywords for sleep (I just use sssshhhh sleepytime)
To begin with on Thursday it was taking up to 20 mins to settle for naps, and 40 for bed, yesterday it was less than 3 mins for all sleeps!!! It feels like the more sleep he gets, the more he wants. If he's really fighting sleep I do swaddle him, he is an arm-flailer and it really calms him - again not for everyone esp older babies.
Dh uses different techniques to calm, he often cuddles or walks around room for a bit to get him to sleep and puts him in his coy asleep. Works for him, the stroking ssshing thing was just instinctive for me, I guess everyone has they're own ways.
If someone had told me on wednesday that I would be writing this about my baby so soon I probably would have laughed manically and/or strangled them, I certainly would not have believed it. I thought we'd co-sleep for years!!! Instead, I am so confident in his sleep that his cot us now in the nursery (with mattress on floor for me and dh if we need it ). I'm typing this on iPhone during night feed - sorry for any typos)
Anyway, hope that answers questions that people asked me. Like I say, I know a) my schedule is nothing new or exciting and b) it sounds implausible that it worked so well so quickly but if you have the smallest feeling that your LO is overtired I would thoroughly recommend trying something similar in terms of early bed time and no more than 2 hours between naps. As he catches up on sleep debt the naps should lengthen so eventually they will naturally cut down to 3 and the last one will just disappear.
Anyway I hope that answers the q's people asked me.
