I have 2 dds aged 5yo and 2yo (this month!).
In the past 2 weeks, dd1 has had a diahorrea bug that lasted a week, followed immediately by a vomiting bug that has slowed down, but is still with us 5 days later.
Dd2 had a separate diahorrea bug; caught dd1's diahorrea bug and now has a cold and chesty cough.
We are all vegetarian. Dd1 is a fussy eater to say the least. I've been cleaning shit, sick and snot up for the last 14 days and now it's the Easter holidays, I want to GO OUT and enjoy our time ... clearly, their immune systems are suppressed, hence bug after bug after bug. Please advise me on how to boost their immune systems.
