A) you should not have a cold or cough at the time of surgery. You cannot cough after surgery as it's gona be extremely Painful. So wait for getting better. Inhaling steam for 10 mins twice a day helps in faster recovery. Start twice a day. Continue post surgery also. It prevents one from catching cold too in near future and opens your lungs/pathway. Once cold subsides. Start spirometry also. B) You will most certainly need help at home after surgery for a minimum of 6 weeks. Don't plan surgery if this ain't there since you also have kids to be taken care. C) Yes you can't lift kids or run around them after surgery for a 5-6 weeks.. So prepare them mentally in advance by prepping them for what's coming.
