How do you handle two kids under 2? I'm absolutely terrified of what's to come 😱I don't like not being prepared. I'm gonna have to handle them on my own all day while hubbys at work. For you moms already in this situation, what's your method? Schedule? Naps? Etc. I attempted a couple days ago to watch my 2y niece and my daughter couple days ago & it went terribly. One starts to scream and cry and then the other one starts, can't hold both of them at the same time because my daughters insanely jealous 🤦🏼‍♀️ I rocked both of them to sleep, set one down she cries and wakes the other and then she starts crying & repeat 😭 idk what I'm gonna do when I have a newborn & my almost 2y together home alone. Can someone give me some tips?
