Myself and DH were talking this evening, we were saying pre kids we don't ever remember being sick, we were never at the doctor or on antibiotics.
We now have two small kids and we seem to catch everything they catch. I mean it has eased, but for example I've needed an antibiotic maybe once a year the last three years (I currently have a throat infection and feel like I have eaten a shard of glass - kids had it last week).
For those with slightly older kids - tell me it ends! I think in general I'm pretty healthy.
