My almost 8 month old has always been an excellent sleeper. From 12 weeks she's gone down awake at 6.45 and slept through til 6.30. She has never woken crying, just chatted until I go through and get her. The last few nights have been a nightmare. She has gone down as usual but woken crying two hours later then will only settle in bed with me, but still wakes crying every couple of hours.
She doesn't appear to be in pain, is happy throughout the day and naps as usual. She is a bit clingier than normal but nothing ott. I know a couple of nights is nothing compared to what some babies are like but it is so unusual in my baby. I don't remember a sleep regression around this age with my eldest but she was an excellent sleeper too.
The timing does seem to fit in with a wonder week but I'm not sure I believe in them as we haven't had this before! Any insight would be appreciated!
