A.S.
I had the same problem when my son was that age and when i spoke with the dr. she told me that by that age they know when they are hungry or not and that it was very normal for there feeding habits to change at this point.i was actually told not to force it on him because then you get into the problems of overfeeding. my son is 8 1/2 months now and even though his feeding habits include eating a lot less he is still quite chubby and very healthy. he for months now lets me know when he's hungry. hope this helps relieve you a little.
