I always tell people that if they're going to do baby-led solids then they need to offer their babies nutritious, healthy foods. I'm shocked to hear stories of people who claim to be doing baby-led solids regularly giving their babies junk food. I am passionate about Buttercup loving healthy food. That is why I almost always give her fruits and veggies, and portions from our own healthily prepared meals. Sometimes, though, there is no food in the house. And for those times I am thankful for peanut butter toast. This isn't a regular food of Buttercup's, but I do bust it out when I haven't got much to offer her in the protein department. I use Smucker's natural PB, because it only has one ingredient (peanuts, duh), and I put it on whatever whole wheat toast I happen to have on hand.
I mention in my previous post on spreads that the American Academy of Pediatrics has lifted their allergy "ban" on peanut butter for babies. If you have a family history then be more cautious than I am. I do make sure that I don't spread the peanut butter too thick, as that could gunk up the windpipe.
When Buttercup was 6ish months, I would give her long strips of toast (look how teensy she was!) to make it easier for her to handle. But, now I cut one-inch squares for her. It is easier for her to eat, and less messy since she isn't squishing peanut butter in her fists.
Buttercup does love her peanut butter and will eat 3/4 of a slice of peanut butter toast, all the while making smacking noises with her lips. Very funny. And, in case you're wondering if toast is too hard for babies without teeth? The answer is "no." Babies have so much drool in their mouths that toast instantaneously turns to mush.
PROS: good source of protein and easy to prepare
CONS: messy hands
