Someone has always been sick

When I say it's always something , I'm not making it up. Since my boy was born in July my 2 year old has had a cold, then I got some stomach bug, then my husband did, then my toddler did. Then again I had gastric issues, then my 2 year old started getting his 2 year molars waking up A TON. Then he got a Stomach bug again last night with a high fever. I'm telling you something's gotta give here we just have not slept at all since July because it's always been something, someone has always been sick for the last 3 months.
