on weekdays, ds gets a shower with me or dh to save time. In his infant tub, he always ends up soaking us anyways, so it's impossible to bathe him like that on a rushed morning.
Just a tip, i don't trust myself to get out of the tub while holding him, but there have been a few occasions where I've had to do it alone. (got pooped on)
After the bath, I drain the tub as well as I can, and put a towel down on the floor of the tub. Put DS on the towel (making sure that there is no water pooling around him, get up, and then get out, and then lift him out.
the downside to this is that you don't get any time alone in the tub to get clean.
