We loved our hammock and used it for both our babies.
There is a massive thread about them somewhere. I'll dig it out when I get a moment.

As for the baby bath - I found it a total PITA. I ditched it when DS1 was about a month old in favour of showers together or a very shallow bath and never regretted it for a moment. I used it to soak clothes in for a while then freecycled it to a single mum-to-be. It was a waste of money and resources.
