Don't be afraid to buy other nappies, you don't have to stick to pampers, cuddles, huggies. You are going to use a lot of them, and a lot of people will swear blue murder that this brand is gods gift to your baby's bum. But at the end of the day get the best for your wallet and the baby's bum.
Get an Angelcare dustbin or something like it, it can hold a lot of dirty nappies, you can tie it up at the end and chuck it, it has a seal that keeps the stink in it. Nappy bags don't always work so well and end up clogging your dustbin. Get a microwave steriliser for the bottles now, it will save a lot of time.
Speaking of bottles, don't always go for avent, nuk etc bottles, a good bpa free one will do. You will end up going through bottles too and having to fork out a lot for them starts to hurt. Cold water is great for washing the milk out of bottles for a pre-rinse.
Wet wipes, if your baby's bum is sensitive to wet wipes, you can use cotton wool dipped in cooled rooibos tea, or try find a more gentle wet wipe, some of them are harsh.
Clothes also don't go for pricey brands, go for what's practical, babies outgrow clothes quickly, you won't understand how quickly until you see.
Take everyone's advice, listen to them, you don't have to follow them, but at least you've listened and can make up your own mind, a lot of people have a lot of advice, but a lot of the time it won't work for you. It's best to take little bits from everyone and make your own. Every child is different so is every parent
