I am also a mother carrying twins. I found out a month after finding out I was pregnant that I was having twins. I almost fainted when I found out. for lack of better words It felt bitter sweet. I was scared, happy, excited, nervous, a bit of everything. Im 33 weeks also.
I think it all came down to money. How will we afford twins, and just buying a new home that became too small over night. Oh boy. Both my husband and I work full time jobs, and I have 2 other children 14 and a 9 year old.
Its scarry, I drove myself crazy for months, then I realized this is how I felt with my second and it all worked out. I guess what Im trying to say is that when they come we'll learn to do things differently to get thru and pray to the Lord to help us thru the days ahead. God does know what he does. We are the chosen few to have this blessing of twins and even if you have doughts for every negative thought think of something possitive. Try to change that around yourself in your mind and heart.
As far as things for the babies ask around find out where there's a twin get together in a church or something in your community it will help you thru it and also if someone is done with their baby stuff im sure they'll pass it on to you. I got all hand me downs from mothers with twins and let me tell you it helps.
God Bless you. ( it will be fine)
