Or you can add fruits to your pap as well

Exclusive breastfeeding is the best for your baby But if you are unable to do so you can start with a good baby formula if your baby isn't taking it, you can do homemade paps (the one I used was millet, guinea corn and yellow maize pap) add soyabeans powder (homemade using soyabeans, Unripe Plantain, and crayfish) to it and baby formula to it. Or you can make blended fruits like blended banana and formula, pawpaw, blended avocado pear with formula, blended boiled carrot with formula.

My candid advise......... Try and do exclusive feeding for 6 months it helps
