#asktheexpert Hello, my baby is 1.5 months old. she spits milk sometimes a day but I know that is normal but other than that I have seen her milk getting back into her mouth and she swallows it back but it makes her very uncomfortable. Even in sleep it happens and then she cries for a while. Her father and grandfather also have the same habit that unintentionally their food comes back to mouth after some time of having food. But I don't know if it is genetic or not. please help
