Thanks for your replies.
Debra - we actually started with the Gina Ford routine at 3 weeks and it's only since then that I heard about the BW and read the books, taking tips that fit in with the routine we already have. Feeding routines have always been good, and my daughter now happily goes 3.5-4 hours between feeds and has just cut out her dream feed (which was fairly small anyway) in the last couple of days, so she's taking about 8oz per feed over 4 feeds a day. She hasn't even increased her daytime feeding volumes as a result of dropping the dream feed. As I said already, her weight gain has always been good (too good perhaps!), so I'm confident she'll continue to thrive without this fifth feed. I hear what you say about the 3 hour BW routine perhaps still being better for a spirited baby at 4 months, but to be honest I'm reluctant to change the feeding pattern as I feel introducing more feeds during the day would be a step backwards.
Our daily routine goes as follows:
8am - wake up and feed (normally already awake from about 7.40, lies in cot cooing and chatting to herself until I go in), then get dressed and play under gymini a while, sit on my lap while i breakfast etc.
9.45/10am - seems to start getting tired, so to nursery for nappy change, wind down (hah!) and bed, normally asleep by 10am
10.35/10.45 - wake up (I'm happy with this nap lasting 45 mins as this is the GF routine that we've been following since the early days), normally nip out briefly at this point to do any grocery shopping
12pm - feed, then a low-key play with soft toys etc.
12.45ish - starts getting tired so take to nursery etc. and put to bed, normally asleep by 1pm-ish, the 'ideal' would be to sleep for 2.25 hours
BUT 1.30/1.45 - wake up suddenly screaming, spend anywhere from 30 mins to an hour trying to get her back to sleep, sometimes manage it sometimes not
3.15 - wake up (if asleep!), feed at 3.30
sometime between 5 and 6 - catnap of around 15 mins (if she slept ok earlier), otherwise about 30 mins, perhaps while out for a walk
7pm - bath, feed (in nursery), bed by 8pm, though it can sometimes take a bit longer to get her down
I always let her nap at home in the morning and try to be at home for the lunchtime nap too (perhaps one day a week I might be out and she sleeps in her puschair lying flat). So I'll keep this up as long as it takes to improve things. As I say, I'd rather not change the feeding pattern unless you really think I need to. So do you think that if I start putting her down for naps fifteen minutes earlier before I even spot any tired cues, at 9.30am and 12.30pm for example, she'll get better? But then she would be going to bed pretty much as soon as she's finished her lunchtime feed, which I don't think is ideal. Please let me know what you think. Thanks again.
