Hi Clare and welcome. Congratulations on your LO and well done you for persisting with breastfeeding
. ((Hugs)) for the tough start you've all had though.
As I'm sure you know, your LO is only 9 weeks corrected so is still very tiny. This means she will still likely need quite a bit of help to settle for sleep, but the good news is that "bad habits" aren't really such a bad thing at this age, as long as you have in mind what you're aiming for eventually.
So with breastfeeding, feeding 2-3hrly will be normal for some LOs at this age. She may not be able to manage 3h so don't push her to do that if she's hungry earlier. Most babies can probably manage 2h though so if she's not even doing that yet, maybe just extend the time between feeds slowly, holding her out perhaps another 5 mins every other feed.
In terms of establishing an EASY routine, I would begin by feeding at WU and then watching her for sleepy signs. When you see them try to to settle her down for a sleep. It's up to you how you do this. I'd suggest using shh pat or a variation (
Shush-pat - How to), perhaps aiming to get the first nap of the day in her cot. Although Tracy said to start as you mean to go on, in practice many of us work on maybe one nap a day in the cot at this age, then use other means eg pram or sling to prevent too much overtiredness as the day goes on. The only thing I would try not to use too often is feeding to sleep. It will happen, inevitable with such a young LO (says she who has just pretty much fed to sleep an overtired 11 week old
), but maybe try other things first.
Have a look here for average A times:
Average A times- BOOKMARK ME!! Bear in mind they are just averages, some babies will need more or less, and also because she is prem her A times may well be closer to her adjusted age of 9 weeks. Don't keep her up just to stick to a routine - even with an hours A time she could still do a 2.5-3hrly routine with 1.5-2h naps. An overtired LO is much harder to settle.
Take it easy on yourself and her, don't try to do everything all at once. If the nap attempt is getting you both worked up, give up, take a break, get her to sleep in her pram and try again when she's a bit better rested and you feel ready. There are no "bad habits" that can't be undone
Hope that helps to start x
