Hello everyone! Girls, there's a question that has arisen. Where to put two babies? The older daughter doesn't sleep in her own bed. I haven't been training her since birth. I want to train the second baby immediately to the crib. How do I do it right? Or is it better to train the daughter first and then put them all together to sleep? I just think the daughter will be upset and resent that another baby is lying on her place. Maybe I can train the baby to sleep right away???‍♀️ How did you organize sleeping places for your children?
