Can we adults drink the remaining of what is left of the formula milk when our children can't finish drinking their milk? Sometimes my LO can't finish the formula milk that I've prepared for her (14 months) so I just drink the remaining amount of milk left thinking it is such a waste to throw away . But my mom told me we adults shouldn't drink our children's formula milk as it is not suitable for adults . She said she have a Friend Who did that And resulted in high blood pressure. Is it true ?
