As long as he is keeping some down G he should be ok. Got any icypoles? Small sips are better, more likely to stay down.

Gastro bug is a shocker. You can still be contagious for over a week after the symptoms stop. My OB asked me not to come in for a week after i had it for that reason, I thought it may have been overkill but we were spew free for a week, my dad came to visit and he got it 6 days later.

Have you got some antibacterial hand wash? Use lots.

I feel so sorry for you, you've only just got over L's sickness.
