I made these two sets for my nephew and the little rascal outgrew one of them already! I'm glad I made the one with the animal print bigger and he was wearing it today.
These are basic pjs, I liked that the sizing started at 1/2 year which is what I used for the set that fits(I had shortened the blue set). The pattern asks for knits for the top but I used flannel for both pieces, the neck opening is wide enough that the stretch is not needed. I used packaged bias binding for the neckline.
