A pair of Quick Change Trousers, 3 month size, from Handmade Beginnings by Anna Marie Horner. He outgrew these pants about a month ago.
A slightly modified Tummy Warmer vest, size 3-6 month, knit using S. R. Kertzer Down To Earth Cotton. This still fits but it's getting short and snug.
A sunbonnet by Purl Soho, size 0-3 months. This is too small for him, but I made him wear it for a walk last week because all his other hats are too big.
Ethan is sporting drool bandanas most days now. He is teething and drooling like crazy, and these are much easier to make than bibs. I used this tutorial by How Does She. I started with a 12.5" square, because I have a 12.5" square ruler.
