This was my list from last time, with amended notes. Feel free to save/print/copy and paste into your phone!
Changing & Washing
Essentials:
Changing bag - any bag is fine! I got a cheap backpack from Decathlon. If you do bottles, you'll want an insulated pouch, but you can buy them separately.
Changing mat - you could just use an old towel, but a mat is more comfy.
Nappies x2 pack - size 1 (not too many - they go into size 2 v fast)
Wash soap - I looooove Weleda Calendula, but any gentle soap is fine. You can also wash them with water.
Wipes x2 - get MORE! Amazon do a big box of 18 on subscribe and save, which is about 3 months' supply, or take advantage of supermarket baby events. Or get washable ones :)
Day outfits/sleepsuits x6 - I actually needed more, because they need full-body clothing for the first 2-3 days and then it went into autumn temperatures within a week of him being born.
Vests/short rompers x10 - it was summer, so I envisaged him wearing just a vest most days/nights.
Cardigans x2
Sunhat - TBH can't remember if this got used, I think not until the second summer really.
Cotton hat for newborn (hospital)
Useful:
Nappy bags - for poos - didn't need straight away, newborn poo doesn't smell plus they are a suffocation hazard.
Changing table (DH wanted)
Baby bath (DH wanted)
Flannels/wash mitts
I want this:
Travel change mat
Nice to have:
Storage boxes for change table
Towels - I really liked having the special baby towel, and you'll probably need a couple extra just due to having an extra person. So would probably move this up in priority. But you can def use your ordinary towels.
Entertainment
(No essentials in this category - and everything is non urgent and can be postponed)
Useful:
Play mat - somewhere safe, clean, comfy to put them on the floor (a blanket works as well)
I want this:
Ring seat - I meant the Galt Playnest. It's great because you partially deflate it for a younger baby and then when they can sit it helps them sit up and play with toys. But better for their posture than a Bumbo.
Bouncy chair/swing/rocker (non urgent)
Nice to have (some things fulfilled more than one purpose!):
Some kind of cloth book
Any toy with mirrors
Rattle
Hanging toy, for car seat (like a snake that winds round the handle)
Archway for the playmat (ours had one built in)
Grabable toy
Wrist rattles - these were a total flop!
Soft toy
Scrunchy toy
Something high contrast
Feeding
(I planned to breastfeed exclusively)
Essentials:
Nursing sleep bra x2
Breast pads
Tops stretchy enough to feed in or front-opening
Trustworthy source of BF info
Useful:
Bottles (non urgent)
Muslin cloths
I want this:
Breastmilk bags (non urgent/if I got a pump later)
Nice to have:
Glider chair (non urgent) - never got one
Did not buy:
Feeding pillow (but ended up using an old pillow)
Breast pump (was a wait and see)
First Aid
Essential:
Infant calpol (non urgent but before first jabs)
Thermometer
Useful:
Nappy rash cream - again I like Weleda Calendula Nappy Change cream. It gets used at some point, but you do get a tiny pot of Sudocrem in the bounty pack, so probably non urgent!
Nipple cream - Lansinoh or other pure lanolin ointment. Expensive, so may be worth waiting to see if your midwife gives you a sample/if you need it.
Baby nail clippers - much easier than scissors or big ones
Did not get:
Nose snot sucker thing - I find them gross and weird. Never missed it.
Sleeping
Essential:
Cot
Cot mattress
Cot sheets x2
Useful:
Baby monitor (non-urgent)
Blankets /baby sleeping bags x2
Mattress protector (cot size) x2
Mattress protector (our bed) x2 - recommend before birth in case waters go in bed.
I want this:
Stuff/furniture/paint to decorate nursery (non-urgent)
Nice to have:
Nightlight
Transport
Essentials:
Pushchair with lie-flat function or carrycot
Car seat suitable from birth
Raincover (non urgent)
Useful:
UV-screening window covers for car (our car has tinted windows, so didn't need)
I want this:
Car seat mirror (non urgent)
Soft stretchy sling (non urgent)
Car seat adaptor for pushchair (non urgent)
Car seat base for car
UV summer tent - didn't get/was never in a situation I would have used! But it did become autumn very fast - if you have an earlier due date and a garden, you might want one.
Did not buy:
Parasol for buggy - they are a pain in the arse and don't work anyway. UV sunshades on the other hand are brilliant, but might not be necessary for a UK summer! Beware, putting a blanket over the buggy for shade can trap heat inside like a greenhouse - hazardous for little ones.
