Gosh it can really do your head in can't it?!

I'm kinda with bjrose on this one - if your little one is screaming etc. with being rocked, maybe you could use this time now to teach her to self settle......as she'll most probably fight it to begin with but if you set up a consistent settling pattern and remain persistent with it for a week, maybe 2, you'll most probably have a little angelic sleeper by the end. Yep, am talking about the whole 'controlled crying' thing but its really not as negative as its made out to be I did it with both my girls and they are fabulous sleepers! (with no side effects! )

At around the same age at nap/bed time, we would change our little ones nappies, give them a quiet cuddle in their room, then pop them in their gro bag, tuck them in, say nighty night and leave. If they cracked it, we'd monitor them for the next 5 to 10 minutes and if they were still going, we'd go in, do a quick once over (ie check nappy, too hot/cold, twisted etc) then another cuddle, not as long but still lovely and then tuck them back in. etc etc etc. In the beginning we had to go in a lot, after not too long, it'd only take one check and then they'd be out to it. Now, DD#2 at 13&1/2 months, no checks.

The other thing we did was decided when and how long they needed to nap for. So if they woke up too soon, as in only napped for 20minutes - for a little one that's not long enough so we'd do a quick quiet resettle, the same as when we first put them to bed. Again, the girls learnt to sleep in solid blocks and as they got older we simply adjusted their nap lengths as well as how many they had during the day. I believe the key was giving the girls a rhythm to learn then they knew what to expect and felt comfy falling into that pattern iykwim.

Hard work in the beginning but gosh it pays back in dividends!
Sorry bout the long post! They are just my thoughts lovey but I do hope that it helped a little. Thinking of you and I really hope your little one settles for you soon
