I'm a FTM with a 16 week old girl. Our pediatrician recommends introducing solids at 4 months. I didn't question it when it came up because it was just mentioned in passing at the 3 month well visit and I also wasn't sure what I wanted to do yet. After doing some reading I'm leaning towards 6 months. I know 4 months is pretty common among pediatricians and was wondering if anyone had any information on why they want you to start early. Has anyone gotten this recommendation from a pediatrician who explained why they should do it? Is there any medical benefits or reasons that could merit starting at 4 instead of 6? I like my pediatrician but I want to understand and make a good decision instead of just taking their advice without thought.
