Mollie was a very skinny baby. She spit up what seemed like non-stop during the first few months, and because we used a "nipple shield" for a while to help with her latch, I don't think she was getting as much milk as she could have without it. When we would go out, people would assume she was a newborn, and some even asked if she had been a preemie! After a few months we were able to stop using the nipple shield and she stopped spitting up, and she plumped right up. I hated those comments because it made me feel like I was doing something wrong. Watching Delia grow so quickly has made be so happy, and I'm enjoying having a big baby this time around!
