I need all the help & tips i can get from the mommas on here that have experience. Im having my boy in September and im wondering when do you usually stop breast feeding and switch to regular milk or almond milk? Im not keeping him on the nipple after hes a year old!! Im not familiar with breast feeding and have no clue where to start.
