I thought my immune system was strong as I would not get sick more than once per year and I have not had a fever since my early teens 20 years ago. This changed when our daughter started nursery/playschool in November and she has picked up 4 colds since.  That has resulted in 4 colds for me too as she sleeps in our bed.  That is 4 colds in 4 months.  They have been relatively mild but my anxiety is telling me that I am imuno compromised or something.  I called the local family doctor however they were not interested in any tests and just said it's normal for new parents to pick up everything the todlers bring back which is on average 8 infections per year.  Are there any parents with a similar experience?
