Yep - I have taken days off to mind either of my girls if sick etc. DH's work is very family friendly and since he has about a gazillion carers/sick days accrued he usually is the one to take the day off. The only times I do take the day off if he is away which is fairly often unfortunately.
For my work - they are ok with you taking time off too look after kids... it is family friendly but they are even happier if you make up the time elsewhere. I had to take yesterday off to mind my DD2 as she was teething really badly and quite upset at daycare on monday. But work is happy for me to go in on sunday to make up my time.
hope your bubba is getting better VP.
