I think at one years old you can start giving them milk... i exclusively breastfeed but i will stop in the summer since its getting harder for me and im exhausted i had a baby back to back and fed my first for 2yrs and than started feeding this baby..please dont judge..im also having other problems like back.. anyways i want to slowly ween him off not fully till the summer. But he does eat solids and started eating what we eat... rice veggies fruits..
