I'm glad to hear your DD is doing okay, LBH - quite right to get her checked.
Thanks for the advice on CC too!
As it turns out, we started last night, without intending to, but that's the way it happened. DD woke briefly at 23.10, went back to sleep without parental intervention, then woke again at 00.00. I tried giving her a feed/nuzzle to resettle, but she just started to yell when I tried to put her in her cot, so DH came in and suggested he take over. So he soothed her and laid her down, went out, she started wailing and calling again, he waited a bit, went back in, repeat, waited a bit longer etc. It took about 1hr20 (probably no longer - possibly shorter - than if we'd been in with her as per previously) and the longest DD was intermittently wailing for (no actual melt-downs) was about 15-20 mins. She fell completely silent at about 01.15.
She woke briefly at 04.10, wailed for a moment, then fell silent again until 06.10.
So we've resolved to stick with it. No more coming into bed with us first thing and latching on - we'll take turns getting up with her.
Tonight, DD protested when I put her down at bedtime. I initially took her straight out and tried again with the same result. So DH went in again and soothed her, came out, momentary tantrum of about two mins from DD then silence.
I'm hoping she's already getting the message.
And actually, with DH and I both agreed on how to do this, it didn't feel too bad. It helps that DD mostly doesn't have major melt-downs (although it's hard to ignore plaintive cries of "Mummy! Daddy! Milk!" etc.)
