A really solid consistent bedtime routine will help her to feel at ease even when she is in diferent places. Making sure she has had her dinner at the right time so she eats plenty. Start to wind her down with gentle music, stories, cuddles. A nice bath with lavender, take her through to her room with soft lighting, give her her last feed, don't let her drop off, read the same story each night and then put her to bed (obviously this bit will be the hard part for now). Once it is established it won't matter so much if you miss out bits of it if you need to or are somewhere else. You could try putting something that smells of you in her cot.
This is from the Teach Yourself Book (it's by Andrea Grace and is sold in Waterstones and I'm sure elsewhere) and is aimed at helping a baby who is used to being fed to sleep:
Try not to let her sleep after 3pm. Give her a carb rich supper and make sure she has had planty of fluids during the day.
Develop a highly repetitive and consistent bedtime routine. Give a bath and take her directly to her bedroom.
Breastfeed her (or whatever) but do not allow her to fall asleep at the breast. If she does speak softly to wake her up.
Cuddle her and show her the same book each night, if she refuses just show her the cover.
Have a kiss goodnight ritual and put her into the cot awake.
When/if she cries give her as much physical contact as she needs to feel safe. Stroke, pat her,lean right in. Try not to lift her out. The aim is that she goes to sleep aware that she is in the cot and even if you are there this is still very good progress. Remind yourself that any tears are out of tiredness and frustrated not hunger or fear and you are teaching her the skills she needs.
As she enters sleep withdraw the amount of physical contact so that you are sitting there quietly.
You might need to settle her the same way when she wakes in the night.
The book suggests a regime of how to gradually withdraw. Each step should last as many nights as you feel comfortable with.
- Stroke her back, lean right in. Do not rock or feed her to sleep.
- Sit with your hand on her back. If she wants to be stroked do so but cut down on the duration. Try not to touch her as she enters sleep.
- Sit beside the cot and touch her hand
- Move away from her slightly. Cut down on eye contact and avoid touching.
- Place her in the cot and then leave. You may have pop in a few times to reassure her.
I realise it is not exactly the same situation but thought it might be helpful.
