Op, if you are worried about bottles, get a tommee tippee perfect prep. I would say it is hands down the best bit of kit we have.
It is unsafe to make bottles in advance. You can make a bottle but it needs to be used within two hours. Your family may do it but it carries the risk of salmonella and other bacteria which adults can cope with but little babies cannot. The formula needs to hit water at a least at 70 degrees, be dissolved in that water, then topped up with cool boiled water. That is why the perfect prep is a godsend.
Get a close Caboo sling. Life saver. All 8 of our NCT babies lived in them.
Hire a bed nest- look into it. Moses baskets are very short term and I don't know many babies who like them!
You don't need a changing table. We never used ours.
Sleepyhead is good for the very early days for nap times but they say it is not safe for overnight sleeping. I bought one and actually only used it twice, but some friends swear by them.
Don't use your carry cot every day for overnight sleeping. I do t know why but although they say they can be used on trips or whatever, the lullaby trust says they are not safe for regular overnight sleeping as they don't breathe the same as a purpose-designed sleeping item, and so increase the risk of sids.
You need a monitor.
You need a room thermometer.
I would say six bottles would be good. If you buy MAM bottles you can sterilise them in the microwave. After six months they can just go through the dishwasher.
Don't bother with toys until much later; they really aren't interested.
Get a u shaped nursing pillow, it saves your back when feeding and also can be used to prop them up etc.
Bouncy chair helped ours nap
Play mat ours loved- still does if we let him.
Almost all you can buy post birth when you find out what kind of baby you get!
