My 12 week old DD was generally going to sleep around 9/10, waking at 3 and 6 for a feed and waking for the day at 8. We also had a decent routine of naps during the day starting. She has sleep in her co-sleeper cot next to us since we brought her home without too many problems.
However, for the last 3 nights she will sleep for about 2 hours, then wake every 45 minutes. This sleep is very restless but she isn't bringing up anything when we wind her at night. She has started to sleep so lightly I can't get her to settle in her cot at all for naps or at bedtime. If I put her in either drowsy or asleep, she wakes and cries endlessly. Similarly if I put her into it awake, she again just cries. Previously she had generally settled fairly easily with a bit of help from us with a band on her tummy. She does seem hungry when she wakes at the moment but I may just be imagining that in desperation to get her back to sleep!
Surely it is too early for signs of the 4 month sleep regression to be starting? I can only presume it is a growth spurt but it is unlike any of her other growth spurts! Any thoughts?
