a week of fun then sickness AGAIN

Adam had last week of work and we spent our days filled with lots of family fun times. Trips to the beach, park, bike rides, baby chinos. It was a great time until Friday when Deacon woke up with the same sickness that knocked us around just a few weeks earlier...
Since then it has jumped onto Maisy and then yesterday struck both Adam, Baylin and Me.
HORRIBLE  - that's the only way i can describe it. 5 people all sick at once.
Adam was great and helped with the kids alot yesterday and let me sleep.
Today we are all feeling a bit better so I'm hoping things only get better from here.
If anyone can recommend a way to cleanse my home id love to hear as two sickness bouts within a month is two too many for me.
Hope you are all well :)
