Formula is okay for 6 months, then later you can begin with banana, Dal paani, pureed apple, curd

If she is on formula u can start at 5.5 months...start with steamed mashed fruits like apple or banana...or else daal water..rice water..

She is taking formula milk and i am working women too.

Wait until completion of six months dear. You can start preparing though if u really want to wean off after six months. Many moms breastfeed even beyond six months but it isn’t mandatory per se.

Only breastfeed till 6 months
