Guilt for wanting to formula feed

Jody
Everyone is supporting me on my decision to stop breastfeeding, but I feel So guilty! Im stopping because she has been pooping green mucous blood & i have stopped eating & drinking dairy products & all the other stuff.. Another reason is i have had 2 infections already & my obgyn said i should start weaning her off because i will get more infections..... I feel so guilty.
