exclusive breastfeeding has no time frame. Its what you feel is best for you and your baby.. Generally you introduce foods to your new addition at about six months but stay away from honey until the age of one. But every baby is different, baby rice and oatmeal can be given to baby a little earlier....everything just depends on you and how you feel your child is growing.
Im exclusively breastfeeding my daughter until she hits 6 months before i try to introduce a bottle, but lately I have been preparing bottles with milk in case i have to leave my daughter behind due to an emergency or something and i cant nurse her right away.
The question i need answered is how do you introduce a bottle to a baby after all you have done is breastfeed?
