I have heard that when babies hit about 4-5 months of age, they can revert back to being 'catnappers' or are difficult to settle. I haven't hit that stage yet, but when we do I was told that sometimes you have to go back to "square one" and re-start the old settling technique you used to get bubs off to sleep in the first place. For us it will be 5 minute blocks of listening to Nina grizzle and 'chatter', then going in, replacing the dummy if she wants it, giving her a cuddle and putting her down while she is awake.

She has already started waking about 2 hours after she goes down at night, but we just re-settle her (trying not to take her out of the cot unless she is upset). During the day I am more flexible about her catnapping and just try to get things done with her jumping in her jolly jumper!!!

Maybe at this age they are going through some changes in regards to energy expenditure and therefore their sleep patterns are changing too. Hopefully keeping her active when she is awake is the key to her sleeping through the night. If she wants to catnap during the day then so be it...as long as she keeps sleeping through the night!!!!!
