This is my second go at these suspender shorts. They are from Sewing for Boys (the book), and I made them for my baby. Here are the ones I made for my older son. I made these in the same fabric, including the same fabric for contrasting waist facings and pocket linings. I made my own buttonhole elastic again and used snaps instead of buttons.
I made these in size 12-18 mo, and was quite pleased the book went down to this size in the shorts. There have been a few patterns I have wanted to make for the baby and they weren't sized down far enough.
