If money gets tight and they can't afford baby food they can purée regular food for the child. There's alternatives to diapers and wipes too if needed. Not formula though .... Makes me wonder why it doesn't go on sale (or at least here it doesn't. )
Sure, there is WIC but personally if I were to go to the WIC office they would laugh at me trying.
**this is NOT a post to say that's why you should bf... Just something I realized about formula***
