I have just had to stop breastfeeding my just-turned 11 month old DS rather traumatically tonight after he bit me so hard I had to pinch him to get him to let go 
.
I had planned to continue bfing until 12 months and then move to cow's milk for his evening feed. So now I've had to stop a month early, can I still go straight to cow's milk or do I have to use formula first? I would rather not faff around with formula (or pay the inflated prices) but don't want to go straight to cow's milk if I risk causing allergy/digestive problems for my DS.
Any thoughts?
Thanks (am feeling a little blue about stopping bfing so suddenly so am trying to be productive to take my mind off it!)
