Two Qs for you guys (possibly related)... Right now we bathe him in a Primo bathtub, placed in the tub itself. (We live in NYC so not many other options...) (http://www.amazon.com/Primo-340W-EuroBath-Pearl-White/dp/B000056OV0/ref=sr_1_1?ie=UTF8&qid=1339617500&sr=8-1)

a) My 10-month old has started to stand up and try to climb out of the bath, even though he otherwise seems to really enjoy it. I usually understand this to mean "end of bath, Mom!" The Q is, has anyone found a way to stop this?

b) This might also be a sign that he's outgrowing his current bathtub (the Primo). What do people buy as the baby's next bathtub? A bathing seat? Just the regular tub with a no-slip mat?

Thanks in advance!
