LO is 5.5 months, and up until a few weeks ago we were still bathing him in the kitchen sink. Well, he's outgrown that, so we are trying to bathe him in the big tub. I've gotten in with him a couple of times, but as I don't want to take a bath every day or fill up the tub that much I'm trying to bathe him from outside the tub. It's just a bit awkward, whether I sit on the edge, or sit on the floor, or try to sit on the toilet. I have bad knees so it is difficult for me to squat or kneel. Any tips or tricks for bath time?
