I'm just curious what other moms think. Is this safe in your opinion? (Read desc.)

So somebody asked for suggestions on how she could take a shower while she has a 5 month old. Somebody suggested bringing the highchair into the bathroom, giving him snacks and taking a shower. Then, she said it's fine as long as you rinse your hair quickly and have a clear shower curtain.

Like am I crazy or is that unsafe? All I can picture is the mom trying to get out to her choking baby, slipping and falling. Plus. Isnt 5 months a bit young for snacks?
