I did the NCT course, but I found it was massively focussed on the giving birth part more than practically how to look after a baby (although they did do quite a bit on breastfeeding, and that was helpful).
The good news is, tiny babies feed, sleep and poo. So all you need to for the first 6-12 weeks is:
Babies sleep a LOT to start with.
The umbilical stump is gross. It basically rots and then drops off.
How to change a nappy - just have a go on a doll once, you'll be doing it 12 times a day and you'll be a pro by day 2. Their poo is like sticky black tar fora day or two, then goes green and finally yellow and M ustardy.
How to feed baby - if you're bf you need to hold them tummy-to-tummy (not tummy upwards) and nose-to-nipple (so that they open wide and get a good mouthfull of areola), if you're bottle feeding honestlyI'd practise a few times as it's stressful and take a long time unless you have a machine for it.
Burp baby after a feed with a muslinor small towel to protect your clothes. Rub/gently pay until theyproduce.
Cluster feeding and/or colic can make the evenings around 3weeks-3months difficult. Plan to do nothing but comfort your baby. You may be pleasantly surprised, but assume you will be watching some box sets....
A nice stretchy wrap/carrier is a godsend for the first few months. Most babies don't like to be out down, but will merrily sleep for 3+ hours strapped to your chest.
Nighttime sleep - decide what you want to do, but be flexible as long as it is safe. Babies need to sleep on their backs and not have pillows or duvets. My personal preference is a side-car cot and baby sleep in bags.
My go-to for my first was the What To Expect in the First Year book. It's massive and I found it really helpful. But do remember that babies don't read the book.... My 4 have all been different.
