Estwd2:Honestly she'll be sitting up on her own in no time, so I wouldn't buy yet another tub. I'm surprised that sling didn't hold out for longer. I had a different kind of tub, but the sling lasted until she could sit up on her own. It might suck now, but it'll probably only suck for a few more weeks. I'd personally stick it out.
Thanks!
I'm sure we could have continued to use the sling longer, but she was starting to look really uncomfortable and squished up!
