Everyone tells me not to worry about it, and that as long as the baby is healthy (and is actually measering a little big via ultrasound) that it is getting what it needs. But every now and then there is someone that tells me that I am not gaining enough weight, and shows me charts of average weight gain and compares it to where I am and makes me feel guilty for not eating more. I am 23 weeks along and have maybe put on three or four pounds. I eat fairly regularly, whenever I am slightly hungry, I snack. I eat healthy foods, I get fairly regular exercise, I don't own a car, walk a lot. In fact, when I eat something unhealthy, like pizza, I feel slightly sick. The baby isn't used to that kind of food I guess. If I go to long without eating I get heartburn, and immediatly know i have to eat something and then it goes away. I am uncertain if I am getting enough calories each day, but I don't FEEL hungry, and I don't eat empty calories if I can avoid it. According to the nutrutionalist I have talked to I have nothing to worry about. My sister had a similar problem and at one point lost so much weight she weighed in at 99 lbs. Has anyone else had this happen? Any suggestions?
