My daughter is 23 months old and has always been a really good sleeper - settles herself to sleep, more often than not has to be woken in the morning. For the last 3-4 months, she has not settled particularly well - we put her down as usual and then any time from 10 minutes to an hour later she wails, we go back to her and give her a brief cuddle (max 2-3 minutes) and put her down again and she goes to sleep. Very rarely we'll have to do this more than once, but that is very much the exception. This is all very irritating but not a huge issue. Over the last week, she has added waking up between 5.45 and 6.30 (back from 7) and refusing to go back to sleep - she'll wail until we go to her, quiet down as we go into the room and during a cuddle and then wail again as soon as we leave the room.
Last night, for the first time in ages, she added a NW - she was up and down between 11.15 and 3, whingy crying, going quiet as we walked in the room and starting again as we left. There didn't seem to be anything wrong, as the crying didn't seem to be particularly urgent and did stop as we walked in the room. I think she is starting to get her second molars, but I really don't think that this was the issue as it didn't seem like a teething cry.
During the day she sleeps for 2-2.5 hours - I know this is quite a lot for her age, but she seems to need it. On days when she has less (she goes to nursery once a week and never sleeps more than an hour and a half) it doesn't seem to make any difference to the settling or the waking time. She is absolutely exhausted this morning, and practically asleep on dh's knee (at 9.50am!).
We have a 6-week old baby, and I have a feeling that these wakings are somehow linked to that, but I'm really not sure what to do to prevent the NW happening again. I have been trying my best to make sure that she is reassured during the day and that we are doing things to keep her entertained.
Is this just a phase that we have to deal with, or is there something we can do to get her sleeping later and making sure that she doesn't wake in the night?
Thanks for any suggestions.
