I use my wool soakers on my older son at night. He is old enough to leave the tie alone. The baby is allergic to wool, so I crocheted him some acrylic soakers for daytime. He would actually pull the drawstring out, so I started tying it around a stitch in the back. He still unties the bow at the front, but at least he cannot pull it out. I will have to try the side tie, but I really like the idea of tying it inside the waistband.
