Xander is 3 months now, and I was just looking over his records from past pediatrician visits and I noticed that his growth percentiles for weight have been steadily decreasing. At 1 week, he was at 56.38% and at 11 weeks, he was at 32.99%. His next visit isn't until July 5th (he will be 18 weeks).

He is EBF and I feed him on demand for as long as he wants, although now that he's at daycare, he gets a 5oz bottle every 3 hours (unless he's hungry sooner and we send an extra bottle every day just in case). So far, my pediatrician hasn't mentioned whether I need to be concerned or not, but I can't help but wonder if I should be. I'm curious what other's experiences were like regarding the growth percentiles and how important they are. Should I be concerned that his percentile is decreasing?
