Hello everyone. Moms, can you tell me any life hack on how to give a child vitamins in liquid form? I give them through a syringe, but it still spills everywhere ? With iron, it's a problem, I used to mix it with water and drink from a bottle, now he refuses. Today I tried giving it with a measuring spoon and I really regretted it ?
