This is one of my favorite patterns for babies! I traced a 50 cm which is a great newborn size for two sets of good weight twins. I omitted the drop seat this time (but I've made it several times with it and its adorable! I like to change the zipper front to a snap front and in the newborn size I don't bother with snaps at the legs as they are so short! The hat is a long forgotten Ottobre pattern that I sized down to newborn size for my boys.
