Samson's Four Months Old!

Sam will be four months old on Thursday. He just had his 4 mo. check up at the docs yesterday. To my dismay and concern, he is underweight. He should be gaining 1 oz. a day and he's only gained 6 ozs. in 2 months. Doc said not to worry, we'll get him back on track starting immediately. She said, "lemme guess... Sam's a happy, easy going, laid back baby." I exclaimed "YES! Why?" She explained that chill babies don't 'complain' as much as others, and therefore when we feed him 4 oz. at a sitting, its just enough to take the hunger edge off, but he COULD eat more - he just won't let us know. He'll go back to cooing and laughing or taking a mild nap. I felt very bad at first, finding out his weight, but today, i feel better knowing that i'm being the best mom i can be. Sam's just like his daddy this way - Mr. "It's all good!"
