Cooking for baby

I love looking for new books at thrift stores and I found this little gem today for $1. 
Has anyone tried/done cooking foods for your baby? 
This will be my first baby so I'm curious about maybe making foods myself for him/her. 
Any tips/pointers welcome. I'm not sure where to begin and I'm only 14 weeks along so I have time to learn just thought this was a cool idea. 
Now to just find a blender... If you've done this before what else might I need to assist me (besides the literal ingredients 😋) ?
