We tried for 2 months to give the bottle to our son because I was leaving for 10 days. He never ever wanted to take it. I left, heartbroken, not knowing how he would do. Great news, he slept for 8h straight, then took 2 ounces, then fell asleep again. All alone with dad. To all the mothers who go back to work, don't feel desperate. Your baby will know how to manage. I would have loved that somebody tells me that before I left, that's why I'm writing this. It's gonna hard to be away, but I know he 's gonna be fine with daddy.
