My baby is 4.5 months, I want to do BLW and not start solids till 6 months. But I've seen that there's research that the earlier you introduce peanuts, the less chance of allergies, ideally at 4 months. Yesterday I was eating peanut butter on toast while playing with him, and there was a teeny smidge of peanut butter on my thumb, so I thought I'll wipe this on his lip. So I did and he really liked it and I've now introduced peanut. But I really don't want to start solids properly yet. Is this a reasonable thing to do semi regularly until we start solids, to give him regular exposure? Or is it weird?
