we had mono chorionic and mono amniotic triplets. now they are 9 years’ old. all of them are girls.
Hi — great blog! I’m 3 months with mono/di twins and my OB said I should look for multiples-blogs and I came across yours. Your boys are so sweet!
We found out 1wk ago at 17weeks that we’re having triplet boys! I have my anatomy scan Tomorrow so I am hoping to know more then. I think they all have their own placentas and sacs.
Congratulations! I hope you do find out they have their own placentas, that will be less worry for you. 🙂 BBB is the best!
