Introducing Foods...

Amber

What is everyone’s take on when and how to introduce foods. I have been doing a lot of research and I’m reading a lot on how the recommendation is to wait until 6 months and that cereals really offer no benefit to baby. I’m trying to figure out what I should do. My LO was born June 25 so now 18 weeks. Also, should I purée veggies and fruits or just buy baby food from the store?
