April newborns - what to dress them in?

My boy is due the very end of March and I just realised I don't really know what clothes I'll need for him! My first boy was born in the middle of a hot summer, so he wore either just a nappy or a short sleeved onesie.... I've just realised how easy we had it! I've just sorted out and washed clothes from #1 and I have about 30 short sleeved onesies (we were given all of them, didn't buy any!!!) and not that much of anything else (a few bits here and there).

So April mummies, I would love your help... what were your staple items for your newborn? What did they wear:   
1) every day around home
2) if you felt like dressing them up a bit (boys) when you went out   
3) to bed at night (he will be wrapped)

TIA

Weather is a bit changeable in April...

On the cooler days

At home: Long sleeve onsies (with feet)
Out: The cute long sleeve onsies (with feet and socks underneath) and a knitted cardigan and beanie.
Bed: Nightie and socks
Short Sleeve body suit underneath all of the above, as he got a bit older I would put him in cute L/S bodysuits and pants...

On the warmer days

At home: Short sleeve onsies and socks
Out: The cute long sleeve onsies (with feet no socks).
Bed: Nightie
Singlet on underneath all of the above.

I dont remember it being warm enough outside to not have long sleeves etc but it was inside on most april days....but our house living room is all glass so if the sun is shining it is hot.

Jake is a hot bubba too, so not sure if that makes a difference...

The other babies in my coffee group all seemed to have layers on so maybe it was just my child

Thanks ladies, that's really helpful April weather is so weird!

Becks wow that would be awesome if we could borrow some of your newborn clothes, thanks!

JC that would be wonderful, when Morgan's grown out of them - thank you so much! It's so crazy what you have to buy for such a short amount of time eh. And if this boy is anything like his brother, he's gonna be big and outgrow clothes quickly!
