I agree with Twin. You need to get the right balance with the responding. Don't make it into a power struggle and be a dork about it. All you are doing is leading a busy life, and you aren't always glued to your phone.
But I agree, the kids are all important. And if you have had a call - you can always drop your W a quick text to see what she wanted.
