when I got pregnant with my second son I was in the process of trying to lose weight...rather than obsess about my food intake i just tried to make healthy choices and eat when I was hungry...small snacks and healthy meals...i also continued walking...the day I had my son at 40 weeks I weighed the same as my first md appt when I was about 2 mos along....I had not gained or lost a lb... my son was the picture of health and weighed 9.5 lbs...after i had him i weighed about 20lbs less than when I started
