Any Amazon baby wrap is perfect for the first few months. I didn’t invest in any snazzy £100+ one after that, as I was soon pregnant again, and DD1 was just too heavy! My husband uses a Stokke carrier - we got it second hand for £10.
Definitely wish I’d prioritised the manoeuvre-ability of the pram (we changed to a buggy at 6 months old because the other bloody massive thing was a nightmare).
Morrisons or Eco No Plastic nappies.
Mirror for the car.
Sudocrem, bupanthen and Johnson’s.
Infacol/gripe water/calpol. You don’t want to need them and not have them.
Baby grows for the first 4-6 months, but after that, I personally think the baby needs diff clothes for diff weathers/activities.
Playpen.
Black and white books, lift flap books.
Comfort toys.
White noise machine with twinkly lights.
Highchair with newborn attachment so baba can watch you. Also saves you bending down.
Portable nightlight.
Set up a changing table in your room if baby is in there for the first few weeks.
Moses basket was great because it is lightweight and easy to bring downstairs. Baby slept in it by my bedside for the first few weeks.
Two changing mats.
Fold up changing mat for changing bag - get the biggest one you can find.
Nappy caddy - again, the cheap Amazon one has worked great.
At least 4 sets of mattress covers and protectors.
Shnuggle bath is still used at 12 months.
We’ve liked the Tuppence and Crumble Star Wrap, sooo much easier to put the baby into, and perfect for most British weather. We have used thermal snowsuits for the really cold weather, and got lots of use out of them. Still - got them second hand as they can be incredibly expensive and keep their quality.
Woolly booties and thick cardies were essential for a winter newborn.
Cotton wool, a towel and a cup of warm water for nappy changes.
Dummies - if baby doesn’t take it immediately, try a diff shape/size/brand, or try again in another week or so. Took my baby a while to take one, but was a very effective comfort to her after a few weeks, and she naturally rejected it from 5 months.
Chew toys (not Sophie) from about 4 months.
3 swaddles.
It was still cold when she outgrew swaddles, so we moved onto thick warm sleepsuits like this: https://www.next.co.uk/style/ST170410/526194?dp=a&dndl=1&gad_source=1&gbraid=0AAAAADm_5UWY_opfDgbZJZwAzlKVQySDu&gclid=EAIaIQobChMIl9Pq8cWwgwMVdY1QBh3-oAacEAQYASABEgL49_D_BwE&gclsrc=aw.ds#526194
Things like shoes and coats - I would just wait until you actually need them. Your baby might start walking at 10 months, or 20 months, so you really don’t know what you’ll need.
For me, breastfeeding didn’t work at all. So I had wasted a loaaaad of money on all the paraphernalia. I’m not even sure I used the rocking chair in the nursery much, as DD soon took dream feeds lying down - so I’m glad I only got a cheap, second hand one.
DD needed a wearable bib, dressing gown and slippers from 4-6 months.
Towels with the hoods are v helpful, because you can put the hood on their head, allow the towel to fall outside of the baby bath, and pick baby up under the armpits (after 3 months or so. Before that it’s like trying to get a slippery fish out the bath!).
