Do I need to buy a baby coat?

[New2020]

Hi All

My baby is due 1st Nov and I'm hoping that we'd be able to get out and go for short walks and fresh air!

But I'm confused as to what the baby would need to wear to keep warm.

I have a star wrap blanket and I wondered if that with a hat, baby grow, vest and cardigan would be enough? That's for a sling

Maybe layered with an extra fleece blanket if needed with the pram

Or do people buy baby coats?

Never used a snowsuit for a baby, weren't any use till they were walking. Used pramsuits a lot though.
