Need some mom tips for bath time...

Lindsey
My LO is growing too big for her infant bath. We tried the big bath this evening and it was less than relaxing (for me mostly.) I need some tips to make baths in the big tub easier. We tried the laundry basket thing but it kept sliding everywhere. And how do I rinse her shampoo with getting it in her face? And what can I do to save my back in this entire process??? Looking forward to hearing what you all do! Thx
