So I took out the infant insert about a week ago, and now I have a question. When DD2 gets mad, she pushes her legs down like she's trying to stand up/push herself up. When she does that, her feet slip under the waist strap of the Ergo. I've tried tightening it, but even if I have it so tight it's uncomfortable and I feel like I'm giving myself a muffin top above the Ergo strap, her feet can still slip under the strap. They don't slip all the way through to the bottom, but then they're pressed between the strap and my stomach, and if I were to let her keep struggling, they would definitely poke out beneath the bottom of the strap.
Does this happen to anyone else? Is it normal? Am I doing something wrong?
