I know this forum is about parenting twins, but I just had to chime in. I am a fraternal twin (I have a twin sister) and the birth mother to identical twin boys.
And this is where I feel a little sheepish chiming in - they're 27 years old. I'm just posting this as a little boost to all mothers of multiples out there who might think there's no light at the end of the tunnel - there is lots of light out there. I just came back from one of the twins' graduation from the police academy (his twin brother also went into law enforcement). Raising kids, whether they be singletons or multiples just means there are myriad moments of joy that supersede moments of frustration (like toilet training).
My twin sister and my own twins are very special to me (as are my other two kids) but I admit the world of twins is intriguing.
Have fun, lots of fun~
