Hi all and welcome, Navy
Not posted for a couple of days as been too tired, but have been trying to keep up with the posts!
Just to dispute everything everyone else has been saying, we used a bath support for dd and she absolutely loved it! Then when she got too big for it and could sit up we moved to a sitting up support thing one of these which was ok but a bit annoying to wash her in.
Then we moved to our current giant inflatable duck which she is super comfy in and she absolutely loves - she now hates the big bath.
We also bathe every night for the purposes of routine - it helps her get in the right mood for sleep.
On a side note, you're not supposed to wash them for the first 4 weeks, are you? Did everybody that's had babies before stick to this? I did with dd but it felt like ever such a long time.
