My son is a little over 4 months and my pediatrician told me to start him on rice cereal since he's already getting uninterested in milk and she wants to see him gain a little bit more by his next appt. He's doubled his birth weight but I call him my string bean because he's in the 95th percentile for height but skinny (like his dad was before the dad bod ;) ) she also said I could start introducing solids eventually but wasn't sure when that would be. I'm not in a rush and plan on just the rice cereal for dinner and breast milk the rest of the day. I just don't want to be waiting too long and missing signs later that he maybe ready. Thanks!!
