“I still breastfeed my one-year-old baby girl. The baby does not drink from a bottle with a nipple or suck on a teether. Should I wean her off her breasts, whether to feed it still?”
I think, that there would be nothing wrong, if you decided to breastfeed your baby girl even until the child is two years old. However, you should not limit yourself to only the mother's food. Gradually diversify your child's menu, introducing puree soups, groats, and also meat (this can be done starting from 6 month). my guess is, that my little girl does not eat with a spoon. So it is not properly nourished – only with milk. My advice is not to teach her to drink from a bottle anymore, but make it a habit to drink from a cup and eat with a spoon. The child does not have to eat the entire meal this way. Maybe start by sucking the breasts, and finish as described above.
I have to warn you, that weaning the baby in a situation, when he has not learned other ways to eat, can be quite difficult. As time goes on, it will become more and more difficult for your child to give up habits. However, please do not be discouraged and be consistent.
