Help! I need to extend 45 minute naps.

[caro558]

Hi
My 6 month old little girl has just started napping for 45 mins, previously she used to sleep for two 2 hour naps plus a one hour nap. Why has this happened ? she was also sleeping through the night and now wakes anytime between 1am and 4am. She is solely breastfed and was 10 weeks premature, so her corrected age is 16 weeks. Anybody got any ideas ? I'd be truly grateful for any advice.
Thanks,
Caroline

Milliie was on a 4 hourly EASY, but recently she seems to be feeding for less time, but more frequently about 3 hrly.
Today as an example she has only slept for 2 hours during the day broken into 30 - 45 mins naps. Normally she would sleep for 5-6 hours.
