I think its normal?!! With DS1 i had supply issues, and struggled. With DS2 i was determined to do it right, and it worked out fine (ie no supply issues this time) but i never feel full, and even when DS doesnt wake for his first night feed until 2am (so 6 1/2 hrs) since his bedtime feed, i still dont feel full. His weight gains have been awesome, and he is quite settled, so obviously its not a problem.

Good luck. Xoxo j.
