My 2 girls are sandwiched between a big boy and a baby boy.
Since having the two girls, I always had dreams of them becoming best friends like my sister and I are. In the last few weeks, I have really been able to observe a close bond growing.
Although I frequently find them fighting, just as often, I find them hugging, helping each other get dressed or playing together.
This will serve them well, when they need the other to cover for them as they sneak back into the house at 1am. … not that my sister or I ever did such a thing.
