You can wait for 4nths

There is still time for your baby to start walking, so please continue to watch his growth. We still have another 3–4 months for him to achieve this milestone. Since he is already standing without support, that’s a very good sign. Please give him some more time. You can continue with vitamin D and multivitamins as advised. But remember, supplements are secondary—the main focus should always be on adequate complementary feeding. Make sure the food you are providing is sufficient for his age and growth needs.
