Girls, beauties ? I need advice! My son is 7.3 years old, I started giving him complementary food (because he wasn't getting enough milk from me) he likes it! But he stopped taking the breast, not with everything (only for sleep) 5 minutes and sleeps I have a lot of milk Is this because of the introduction of complementary food? Did you have the same? What did you do???
