Nursery said son is sick more often than other kids

I had this with our nursery for our little boy as he kept getting sent home with loose poop and high temperatures. Took him to the hospital as his temperature situation was pretty much every day and turns out he was iron deficient so had iron supplements. He’s fine and fit now but now due to our family diet (we are vegetarian) I give both of my children well baby multi vitamins which gets mixed in with their first drink of the day. Might be worth taking him to the hospital or getting doctor to check him over just to be safe . We are now also waiting for results to see if he is dairy intolerant as he still has frequent loose poops.

I would get his iron levels checked especially if you aren’t feeding red meat. My son (12-24 months at the time) was getting sick constantly and it turned out he had very low ferritin likely from too much milk interfering with iron absorption as we actually eat quite a bit of red meat. Have limited all dairy intake to mornings only now. He also has well baby multi-vitamins and he’s only been sick once since June which a massive feat for us - he was constantly sick before that. Low iron is a major reason toddlers can sick. I’d take him to your GP and state the nursery has flagged he’s extra sick compared to others
