HI, thanks for using healthcare magic
If she is feeding well then the
breastfeeding can continue till she is a yr old.
If you are not comfortable breastfeeding then you can introduce formula which she would use instead of the breast milk.
There are a wide range of formulas available, you can choose one for her age group and monitor to see if she likes it and for any effects (
rash or change in stool habits). If none occur then it can be continued.
You may want to consider starting her on mashed foods now that she is 5 months old. This can be started from 4 to 6 months of age.
Cereals should be started first, this may help with weight gain.
Fruits and vegetables can then be introduced, all mashed, one at a time. Each food should be introduced on its own for at least 3 days to monitor for any reaction.
I hope this helps
