My baby is currently 6mo. Hesitating to start soild food as he is having cough and a lot of phlegm. Starting to lose interest in milk as well. Afraid if start soild food will course him to have more phlegm. Can advise what should i do?? TIA!

It's ok if you delay the food weaning stage. At his age, food is an 'experiment' for him. To discover the taste and texture, and skills related to eating (chewing, spitting, use hand etc). Baby below 1 y/o main food is milk, the other food is supplementary. After 1 y/o, it's the other way around. Since your baby is not well, keep nursing him and start the food weaning when his condition is better and comfortable for him.
