Tips on letting child take a bath alone
Lay down ground rules. (No splashing...ha ha...toys and wash cloth stay in the tub, don't get out by themselves, call mom/dad that you are ready to get out and whatever else you can think of....)
Don't fill the tub too full. I only ever put a couple of inches in when they first started taking a bath by themselves.
Always be within ear shot.
Accidents happen so be sure to put down a lot of floor protection in the form of a tub mat or towels.
I was right there when it happened too, just putting something in the linen closet about three feet away.
I'm not saying that we shouldn't pay attention, just that kids are made to get bumps and bruises along the way. :)
