Love your children they are part of your soul
Being a mom is never easy. Trust me it's the hardest work on world to raise two kids of same age at a same time. Nevertheless is less fun either. But always make sure you don't discriminate amongst your kids. Here's few golden rule to live by.
Love both kids equally
Don't think one is your favorite child, you can't share love like loaf of bread
Be a friend more than a mom, listen to what your child has to say, than being judgemental always
At times you need to be a little stern, to ensure the kids don't pick up any wrong habits. But it's fine to just monitor them especially when they are so young and between the age of 5-12. However with a pubescent child always try a different approach. They may not like you playing a Sherlock in their personal life.
Above all love unconditionally
