Help!!! 7 month keeps waking at 5.30am. Used to sleep 630/7-630. However for the passed month or two has been waking early. Sleeps about 3-3.5 hours a day in 3 naps. Has first nap at 830am (which is a push). Can only seem to stay awake 2-2.5 hours max so don't think afternoon cat nap can be cut out yet. Is weaning now and has 3 meals a day including right amount of carbs etc and still has 4 milk feeds. I have no clue what to try next, any useful tips to try?
