Just for giggles, I picked up the allergy test results I had done 5 years ago this summer.
I was mildly allergic to cats, even more mildly allergic to horses, and dust.
Quite a change for 5 years.
PS - TM, difficult child 2 slept thru the night til he was about a year old, then he quit and didn't again until he was 3+. Now its sporadic. Fun, huh???
