I don't understand how some people react by saying "I don't care if you THINK it's unsafe I don't need your advice." There's a reason there's guidelines for things like car seat inserts and baby laying on their stomach and drinking water before 1 years old, etc. Just because your baby hasn't DIED from it yet you think it's safe? You're going to wait until that point to deem it unsafe even though the death/injury of other babies have already happened which is why there's guidelines in the first place. I really don't get it. If I was doing something I didn't know was unsafe I'd be so grateful if someone told me. I want my baby as a safe as possible. Nobody is trying to "mother someone else's kid," they just want to help you know better so you can do better.
