Mommies of 3!

Mommies of multiple children how did you adjust to having 3 children, day/night time routine, making time for the other 2 . I have managed spending time with my 7 & 2 year old who will be 3 by the time the new baby comes. I just don’t know how to adjust to 3 children! 😢 please don’t be mean and just give supportive advice please even if you have more then 3 children! Thanks in advance!
