I have 3 children, how about you?
I actually am a foster parent to 3 kids and I have adopted 2 as well. 
That's wonderful! I fostered a teenager from 14-18. It was such a rewarding and difficult experience
Wow! Isn't is hard since it's arranged through the government (social services)?
Oh I actually managed mine through family and a lawyer, he was my nephew.
So smart! Regardless "parenting" encompasses emotional, social and intellectual development since they are babies! Still hard into adulthood! 
It is just so many skills to master and balance all at once when you get a kid to take care of.
Yes - regardless if the child is your biologically there are so many intricacies of raising a child!
What's your parenting style? More strict, balanced or easy-going?
English Dr. Donal Winnicott described my style perfectly when he described "good enough" parenting with few prerequisites for a healthy child development
