Hi gopal,
I am really concerned that your child has lost weight.
Illness can result in reduction of weight due to poor feeding unable to meet our body's needs . It would result in depletion of our body stores and hence body weight. But as children recover from illness their appetite also improves and they usually start eating well. They start catching up their previous weight in a short span of time. So don't worry he will regain his previous weight.
All we need to do is give him weaning food adequately. By around one year he should be able to eat all food items which we eat. You can add ghee to his food, weight increases easily. Take care.

hi,
It is highly unlikely for a child of 9 months age to get typhoid fever.. but besides that coming to your question about loss of weight.. it is quiet natural for a sick child to lose weight until recovery.. one is cause of increased body demand and also cause child will not be able to accept the same amount of food as in pre-illness period.. hence if the child has recovered well there is no need to worry as he will regain his lost weight in this recovery period..
diet advice:1. continue to breast feed the child as much as the child wants/ mother can afford to..
best if continued up to 2 yrs.
2.apart from this the child will need a good amount of nutritious complementary food
in the form of mashed vegetables (potatoes, carrots), fruits.. also soft paste made
of cereals/ pulses sprouts which is roasted powdered and a puree is made with
milk , sugar or jaggery also soups of green leafy vegetables, chiken (if non
vegans).. child can also be fed regular home made diet but soft and bland part of
it..
3. do not force feed the child give him/her a gap 2 hrs to 3 hrs for a good digestion..
4. maintain good hygiene while preparing the food for the child as this will avoid
further illness and further weight loss.
