I’ve not long had my first and we massively overbought, luckily someone I knew was having a baby a few months after so we gave a lot away.
What I needed was a next2me in bedroom, cot as he outgrew his next2me quite quickly (sleeps like a starfish). He’s never had a mobile or light as his groegg room temp had a light on. Downstairs we used a sleepyhead on the sofa and then as soon as he got bigger we took him upstairs for naps as it helped him settle into his cot.
Something for swaddling if you’re going to swaddle.
Our chair we got from Argos for £25 and he loved it and the colours to play with and sleep in sometimes.
Soft mats from eBay as you get much more for the price.
DS in now 8 months old and we’ve not long got him a playpen. One of the best buys as he was an early crawler/stander so it’s somewhere safe to leave him downstairs if I need to pop the loo etc as the chair stopped being interesting for him. Upstairs the cot is his safe place if I need the loo etc.
Don’t bother with a changing table, a changing mat and a caddy with your bits in is good enough and much cheaper. We had one in our bedroom and one in the living room, to save moving around too much when he needed a change, we also kept a spare vest and grow in each for poo explosions etc.
Jumperoo/baby walker for 6+ months although my DS was in his walker around 4/5 months as he just wanted to move. It goes so quickly that before you know if you’re rushing out to buy these things so if you have the space I’d buy it ready.
Make sure you’ve got things like snufflebabe, calpol, bottle cleaners, dummies etc. If they’re relevant to you.
Good luck and CONGRATULATIONS! Enjoy every moment x
