Things do seem to have changed a great deal during the last few weeks.
LO is awake for longer & feeding less, she was feeding every 2/3 hrs but now more like 4hrs, but over the last 2 days I have been feeding her every 4hrs even though she is not "asking" for food....is this right or should I just wait until she cries for food?
Having looked at the 4hr EASY it looks pretty much like we are doing that already with regard to activity time & feed times, it just all falls to peices at nap time...although the last few days she has had a couple of 1 1/2hr sleeps, so maybe she is falling into a new routine?
Also during the last few nights she has had a couple of good length sleeps....11.15pm til 6.20 am with only waking once for her dummy at 1.30am. and another time, having a five hour run instead of every 3hrs. But last night was back to every 3 hours again.
I think you are right, this is not a food / solids issue but a sleep / activity / growth issue.
