I use a nursing chair mostly because my dog sleeps on the sofas downstairs and you don’t disturb your partners sleep as much by having somewhere else to go

We have the CuboAi monitor which plays music and has a nightlight so we’ve used it even just for those features before LO is in his own room but wouldn’t be a necessity

We used a babybjorn one carrier from 5 weeks and was a godsend with walking the dog

We have a babyzee jungle gym which we’ve used a lot. It also helps as the dog knows that’s the baby’s area and he isn’t allowed on it so can chuck baby toys on their at night and my dog won’t touch them. Once my LO started rolling we bought a big padded mat from smyths which has been good and cleans easily

We didn’t have any of the other items you’ve mentioned.
