Pumpkin is a great choice to start with because it's not a common allergy and it's great for digestion. You should either used pie pumpkins or sugar pumpkins. I used organic canned pumpkin like for baking and just mixed water so it was thinner. As long as the canned stuff is 100% pumpkin it's perfectly fine.
@Jen oh wow, my boy just turned 5months today, I will try giving him and see if he will like it.
I'm about to try pumpkin with my 5 month old. We got the okay to start pureed veggies and fruits at 4 months so we've been trying a variety of veggies to start with.
I roasted the tiny ones from his pumpkin photo shoot and blended it. It’s his favorite veggie so far
