Little order sleepies mountains zippy

Product Name: Little order sleepies mountains zippy
Size order 6-12 months Good used condition although listed as fair for 2 holes (see pics). One is very small at bottom of leg and other is on Inside of zipper (can't see unless you lift zipper). There are some loose threads along the zipper. After looking closely, I noticed one of these had opened up into a hole along the inside of the zipper. I never saw this when my baby was wearing it or just looking at it from the outside. I think this would be an easy fix (if you know how to sew unlike me!) Smoke free/pet friendly.
