Hi I am a first time mom too, first congratulations for choosing to breastfeed your baby as the percentage is getting low day by day. When to stop bf is between you and your baby. If your baby is more than 6 months of age and has shifted towards solids and accepting it well you can slowly cut down the daytime feeds one by one gradually and replace it with solids. However if you can and if there is a good milkflow, you can continue to bf 2-3 times a day until 1 year of baby's age and after that slowly stop totally by keeping an alternate source of milk in hand, be it formula or cow's milk whatever.
