Leah's Growth

I still am a little worried about Leah's growth rate. She just doesn't seem to be growing like she should be. I hope I am just being a paranoid mother and there isn't anything wrong. She is still wearing size 0-3m clothing, and very few 3-6m. When I measured her a couple weeks ago she hadn't grown since her appt. on May 22nd. Her next appointment in on July 22nd so we will see how she did and talk to the pediatrician then.
