We went and got a really interesting looking bath from Big W - was a bit pricey - and had moulds and everything from newborn to toddler. DS absolutely hated it as he couldn't go under the water as much as he wanted etc, and he would just scream. So I got sick of that and went to a baby shop and got the biggest baby bath I could (its really long and quite deep) and just plain white etc, for around $30. We use this still (and he is just over 12 months old) and he loves it. We have stuck some sticky things on the side and the bottom that he loves to scratch away at, and we put it in our bathtub so we just sit on the floor next to the bath, whilst he plays away!!!! Before he could sit up it was a bit hard on the back, so we bathed him in the laundry sink until he could sit up on his own. Then back to the baby bath in the bathtub. I'm not sure what everyone else does, but it works for us!!
