My baby has just turned 13 months but I can’t remember the last time he wasn’t ill. He’s had broncilitis 3 times, too many colds to count, sickness, rotavirus, sickness and diahorrea and now his chest is currently playing up again, the poor boy doesn’t get a rest. I get that babies are constantly ill but when would you start to think it may be a problem with their immunity?? I have bad health anxiety so I’m just wondering would I be right to ask for some blood tests for further checks and to rule anything else out. Im a single mum and all these sleepless nights for both of us are getting too much
