Hello everyone. Can you advise me please, who drank cola during pregnancy? I didn't drink it for the first three months. But in the last two months I can't stop. Every other day I drink a liter of cola. It's like a drug, somehow. They recently wrote that girls can't quit smoking. And I am included in this too ?Every day I say it's the last time, but within a day my body demands something, I don't understand. My husband scolds me saying that if we have a baby tomorrow, he might be born with a defect. Who drank cola, how does it affect the child? Please help me replace it with something else?
