Simple Joys by Carter's Baby Boys' 6-Pack Short-Sleeve Bodysuit

These cover his body well without pulling down at the neck or up at the legs. He had some Rosie Pope 0-3 month ones that he had to stop wearing at 2 months because they fit like lingerie for lack of a better description. The neck was stretched so that it was like a low cut blouse, and the leg holes were stretched to where they looked like a bikini cut. Meanwhile there was like 3 inches extra material in the width. They looked so ridiculous I had to stop putting them on him.
