Hi Neha
my 10-mth old is changing his feeding pattern too! Not only that he's taking 1 more oz each feed, he actually demands an additional feed at middle of the night! in other words, he is taking 10 oz more than he would normally do a week ago. Also suspect a growth spurt though not sure what it is except from what i read from the internet:
