HV will just drop off the all-important red book (put in hospital bag), probably tell you that you need to breastfeed, and will generally check you're not a dangerous crystal meth addict.
Mine only came post-birth, too, which was weird as everyone in hospital kept asking me for H's red book.
I'm using blankets at the moment but think I'll be switching to a gro bag as soon as I can get to mothercare because he keeps kicking them off. I'm fairly lucky that he tells us very quickly if he's too hot.
Sorry to hear about possible poorly cat - we have a bonkers kitty on our hands. Took her cone of shame off today, 8 days since being neutered, and she's been mental all day. This includes working out how to get over the stairgate at the bottom of the stairs. Not good.
Fingers crossed yours is better soon Alex!
In other news, I managed to get my hair cut today! Actually look 5 years younger. My mum ended up carrying H round the shopping centre as he was grizzling in car seat... he properly turned on the charm and was smiling and giggling at everyone, enchanting old ladies and clearly having a whale of a time. Was very cute biased :)
