The First Years Newborn to Toddler Tub, Blue

I needed an updated tub for my newest baby. I love that this is an all in one just like my previous tub, but it was much cheaper and easier to keep clean. The newborn sling wasn't needed by time we ordered it, but we surely kept it stored away for the next baby. I love that there's two spaces for sitting at different stages- and again, it's easy to keep clean! Our previous tub was all cloth until they could use the tub as a whole for big boy/girl baths. Safety? Clearly no one should be walking away from their baby at any age in the bath, but my only concern is how easily it slides around. My babe pushed against the the tub wall and it slid this tub around. Not much, but enough for me to keep a sharper eye on them. The plug is odd? Maybe it's just mine? It doesn't really drain the water unless I hold the side of the tub up. I usually just dump it all out at once and then leave it to dry.
