I think that there is more focus on children's product at HC. I have shops on both Etsy and HC and I sell more on HC. The price for a shop there is right, too. You can stock all you want for the same low price. Etsy cost to list, cost when you sell and cost to keep your listing from being smothered under all the other stuff. If you plan to advertise elsewhere, you can make the Etsy work for you. HC has a built in clientele with kids and babies. Good luck to you!
