X-posts PJ. Glad it went well. Some vicars are funny about photos taking away from the solemnity of the service. You want a Cafflick church innit, where weddings and baptisms are celebrations, not solemn occasions. Oh well, that's how all my priests looked at them anyway.
If L has a cold and can't breathe or sleep properly and is more clingy than usual, then I would hold off. If she's just a little snuffly and is sleeping fine during the day or with you, then plug in a Karvol vapouriser, rub Calrub or whatever that decongestant stuff is called into her chest and back before bed and she'll be fine. If you think she's teething, give her some Nelsons teething powder and/ or Neurofen at bath time to give it time to work for bed time. Actually, when A is overtired, the Nelsons powder works well to calm her, because it's Camomile. You can practically see it working.
Once she's in bed, then it's up to you. If you go for CC, then how about not "timing" it, but just only going in if she's really demented. Don't be tempted to keep popping in because she's whining or doing "normal" crying iyswim. You might just be disturbing her wind-down by doing that. Some people will disagree with me I'm sure, but I am convinced that when A is very tired, she moans and cries to release tension. I put her down at 10 this morning and she screamed really loudly for about 5 minutes, but I swear it was like the screaming you might do into your pillow if you were frustrated and wanted to punch something. Then she started making Mmmmm noises and dropped off. If I'd rushed back in as soon as she screamed, then I'd have disturbed her and messed her about and stimulated her further. Do you see what I'm getting at? Don't sit outside the door or have the monitor turned right up either. It just makes it sound worse than it really is. And she won't "hate" you. She doesn't hate your mother or the nursery for putting her to bed, does she? She'll be annoyed and frustrated that she's not getting her normal two hours of driving Mummy round the twist whilst she bounces on your bed, but she won't hate you.
For us "extinction" was easier than CC. Cry it out for one or two nights and that was the end of it. Some parents can't bear it. Some babies don't respond to it or are babies that make themselves sick if they cry a lot, so I'm not saying it's for everyone.
Talk to her and tell her what the plan is. I think babies understand more than we give them credit for. Start as you mean to go on with the bedtime routine and stick to the same routine until it's sorted, right down to closing the curtains and telling her it's time for bed.
