I find myself enjoying the kids more as they get older. It's so hard when they are babies. They're cute but until they can start to hold a conversation, it can be pretty lonely as a parent.
You're in a tough time Chrome but it will pass. The twins are getting old enough like you said to start really relating to them which is fun. Your son will soon follow.
But then like Karen noted, before you realize it, they don't want to hang out with you anymore. Not looking forward to the teen years.
