You don't really need both, you can put baby straight into a cot. We just preferred using a moses basket first because it seemed more snug for her rather than a big cot. I would say a baby seat/bouncer was one of our most essential items, ours vibrated and she loved napping in it during the day. The baby bath was a total waste of time, it's so heavy to lift when full, we only used it once and then just used a baby bath support in the big bath. The bath support was fantastic too, it means you have both hands free to wash baby.
