Going from 1 to 3..

Twin moms I need some advice.. I'm going to be having my boys soon and I am starting to panic a little.. I've got myself very prepared as far as supplies goes (I think) and I've been trying my best to prepare my 5 year old daughter for her new brothers. This is partly where I struggle... she is 100% mamas girl. We get our toes done together, occasionally go to the movies, have dinner dates, etc.. she is and always has been a Mommy's girl and since her dad and I are not together anymore she rarely wants to even see him. Only for short visits no overnight stays.. anyways, I'm really worried about her feeling "left out" and like I don't have time for her anymore. I am a single mom. My daughter and my boys have the same dad, but he is not very involved. He has not bought a single thing for the babies since I've been pregnant (I'm 8 months along now) I need some tips on doing all this by myself once the babies come.. going from 1 to 3 seems like such a challenge in ways. And last night I woke up from a dream that my daughter got snatched away because I didn't have enough hands to hold all my babies hands at once..(silly I know.. but hey, pregnancy lol) Any moms have any advice or tips for me? I'm confident in my ability to do this I just worry at times and want to be as over prepared as possible as I am gonna be alone with newborn twins and my daughter (when she isn't in school) most of the time. Do you have a certain product or routine that made it easier??? Any advice or tips appreciated! 💙💙
