My dd is 9 months old and started 2 days a week at a nursery when she was 7 month. It seems that she has been constantly ill ever since. We seem to lurch from one cold, to a chest infection, to a tummy upset and still the constant snotty nose, periodically high temperature etc etc. Is this "normal" or should I be worried? She's OK in herself for the most part although I fear that she is low in weight (getting her checked on Thursday) because she's hardly been able to eat properly for the past month, with a bad tummy bug and then a dose of antibiotics. She looks a bit on the thin side but apart from that is fairly active and is crawling/standing OK. The only time she was completely well was when we had a holiday in Greece!! Any thoughts welcomed but this is really starting to get me down!
