Hi Mrs D, we've missed you!
DD used to get croup on an annual basis, so I feel your pain on that front. Scary, isn't it?
Sounds like you and DH have a similar bug to the one which DS and I are sharing. It goes on forever, if it is, by the way. I'm heading into week 2 and DS is almost into the 3rd week!
I'm holding off on the heating front for now as the house is - just - maintaining a comfortable temp. It's not going to be off for long though, if this wet weather carries on!
