Hope you are doing fine.
1)Product Review(B01DFKBZ5K), (B072JCWTYM) :
>>>Product seems good but there is bit competition with this product so here you need to work little more to get visibility on first two pages on Amazon.
Quality will always be key with this products because of relation to babies/toddler/infant so here you need to put some extra effort. After launching your product you need to get some quick friendly sales with verified reviews to get buy button and more visibility. I guess you need to have a BIS certificate with this kind of baby product.
Let me know if you need anything else!
