Hello Ladies!
I was hoping I wouldn't feel the need to join this thread, friendly though it is....(!) but, hey...
I'm very impressed with everything you're trying to do to improve your LO's sleep and I hope to add/receive some support and tips from/for my own situation.
My DD is 14 weeks, 10 weeks corrected (hello other mums of premmies!) which means, as someone said above, I'm never quite sure where we are in terms of developmental milestones and things like growth spurts etc...
My main problem is the nights. I'm lucky in some ways because I can usually get DD down for the night by 2000 without too much fussing. It's her waking pattern that's somewhat tiresome. The first sleep stretch is the longest - at worst, 3 hours, at best 5 (for the first time last night) after that she wakes up every 1-3 hours (usually with gradually shortening gaps...3 hours, then 2, then 1.5....) until 0800-0900 (which I recognise is an eminently civilised getting up time!) We tried to use her dummy to lengthen the gaps which worked to some extent, but produced the disastrous result of her becoming horribly dummy-dependent, waking up every ten minutes needing it to be replugged - in short, it was much worse for her sleep and mine.
Yesterday I started Operation Remove Dummy, which has been reasonably successful so far, touch wood. Where we were getting a bit cavalier with offering her the dummy, I'm now much stricter, only giving it to her where it seems absolutely necessary to soothe her, naps and overnight. I'm gently taking it from her after about 10 mins and so far (SO FAR...), this hasn't disturbed her too much. In fact, her first 5 hour stretch last night could well have been because she fell asleep without the dummy...
I've also started swaddling her, after thinking she didn't like it. But after a little protesting initially, it does seem to be helping her sleep better (unless she gets her arms free, which is another story!) - Dr Karp's 5S calming technique is also being used as a way of avoiding dummy use and to get her in a calm and - hopefully - sleep-ready state of mind.
Her naps are okay, I've been working on those for a while. Now she naps mainly in her pram (although I've had to bring in Rock And Stop as she was getting too dependent on constant motion to get off to sleep. Now we back and forth until she starts to droop then stop - starting again if necessary, but leaving her to actually fall asleep when the pram isn't moving...so far, so good...) She can seldom manage more than an hour awake without getting tired and teasy, so that's when I tend to get her down. I try and make sure at least one of her naps - sometimes more - is in her babynest. I try to get her to do a 2-hour minimum sleep at lunchtime, often needing to pram rock her on after her first cycle. She also seems to need a 45 minute recharge ending no later than 1800 so she won't be overtired for her 1900ish bed time. Most of her naps are in the 45 mins - 1 hour timeframe.
We have a bedtime routine that includes a bath, a little bit of massage, a lullaby and a final feed. I've noticed if the routine gets out of kilter, she's much harder to get off to sleep.
Overnight she MOSTLY resettles fairly quickly, apart from the recent dummy disasters (which I'm hoping are behind us, but I'm not going to crack open the Champers just yet), it's just the number of wake-ups that is the killer. I usually only change her once overnight, unless she poos or her nappy's leaked and I keep it all as calm and quiet as possible to encourage sleep.
DD is exclusively breast-fed (after a hellish time getting it established) and we co-sleep (with her in her babynest in a side-car arrangement). It means all I have to do is reach out an arm to be able to touch her.
I've got EP's NCSS and I'm using various of her suggestions.
Anyway, I realise I'm not doing badly compared with those who have to cope with loads of screaming, endless re-settling times and non-existent napping...but I'd LOVE a longer stretch of sleep one of these days - for her as well as me!
Sorry that was long, thought I'd fill you all in. Really glad some of you are seeing improvements - but boy, isn't it always one step forward, half a step back with babies??!
