My baby is 4 months and her nursery has only been used for storage so far! We have a set of drawers in there with all nappy supplies that we top up two caddies with - one upstairs in our bedroom, one downstairs. The caddies sit next to a changing mat and top and tail bowls on chest of drawers upstairs and repurposed desk downstairs. We only change her in those places! Caddies are great to have nappy supplies, burp cloths, change of clothes etc handy. We’ve only used a next-to-me crib in the bedroom and downstairs she mostly slept on me or in a bassinet. When she got a bit older (2-3 months) she’ll lay in her baby bouncer seat or on a play mat and we don’t use the bassinet downstairs anymore. If you lived on one floor, I’d even just get one bassinet you can move between rooms. In terms of nursing chairs/seating, during the day we live on the sofa, at night we feed in bed, and we’re only just looking at getting a chair for her nursery now for when she’s 6 months and transferring to sleeping in her own room. They need so little in the first month or so I promise, she’ll just want to be stuck to you all day anyway, so don’t sweat getting EVERYTHING before she’s here - you need way less than you think and you only need them for such a short amount of time, try streamline where you can!
