Girls, I don't know what to do! Before New Year's Eve, my little one got sick ? And I took her to sleep with me for a while (I was worried about the abundance of phlegm and terrible coughing). So in the end, she doesn't want to sleep in her own bed anymore!! Such awful tantrums and crying, and she learned to get out of bed. Now I'm afraid to put her there, what if she wakes up and falls on the floor from such a distance ?? Can you tell me how to do it and what to do? Maybe someone has encountered something like this?
