Sleeping alot

I’ve noticed the last two days by two month old has been sleeping way more than anything, she’s always been an active little baba and I’ve noticed she doesn’t wanna be awake at all whenever she’s on me.

Me and my eldest are suffering from a cold and I thought maybe she’s coming down with it but she’s not showing any signs, having loads of wet nappies, she’s drinking but not loads which I’ve noticed but enough that’s not worrying.

Obviously I know she’s still a baby but its weirded me out how whenever I’m holding her or feeding her she’s passing out instantly.

Could she just be coming down with the cold weve got or is this normal???
