Feeding;
Wait and see how you get on with breastfeeding before buying any bottle equipment. You might not need it and it can be easily purchased on Amazon for next day delivery if you do.
If you are thinking about a breast pump I found Medella best. Again don’t buy before the birth though as you might not need.
Changing;
Wipes- I use Aldi sensitive. Never had any problems with them. I used Water Wipes for the first few weeks on midwife recommendation but will use Aldi from the start next time.
There is a really good bath sponge you can get in mother care that you rest baby on when in the bath. You also need a few flannels/sponges and some sensitive bubble bath. Just plain water is best for first few weeks.
A hooded towel is nice to have but not essential.
Nappies- first size pampers are softest and nicest for a new born. I stuck with pampers all the way through as found they fitted DS best after trying cheaper supermarket alternatives.
Sleeping- decide what you want. A Moses basket will last 3 months max, possibly less. Bonus is tin can bring it downstairs in the day. I used a side sleeper crib until 5 months then into a proper cot in his own room. Downstairs I either used the pram carry cot or a Poddle Pad cushion for naps.
Clothing-
Some plain white vests in newborn, 1 month and 0-3 months.
Sleepsuits again in a variety of sizes. Don’t buy too many as you will no doubt be gifted loads when baby is here! Don’t buy any proper outfits for first few weeks. Total waste as they aren’t comfy in them and they only get sicked or poo’d on!
Oh and finally- muslin clothes. Twice as many as you think you need and then double again. No need for expensive ones, they all wash the same!
