[kat060287]

My lo who is 7 months became unwell 2 months ago with cold & really bad cough which was worse at night. i seen 4 different drs who kept saying her chest was clear and that was it. on the 5th day she ended up in hospital in an oxygen tent for 2 days because her oxygen was low. Last week she started coughing again not as bad but same type and it is getting worse and shes is coughing stuff up. for the past 4 night she is awake most of the night coughing and crying, i have been to drs, walk in and A&E they r saying the same chest clear and there is nothing they can give her. Last night it happened every half hour right through the nigh I am exhausted and she is so upset with the coughing, i just dont know what to do. has anybody got any advice of had a similar experience? x
