If there is one thing that is easy for a mom to do it is to grow weary of the job of mothering. Please don't though. Don't long for other things...
If you are a mom of a new baby don't wish for them to get older so they will sleep longer... embrace holding and feeding them in the wee hours. They are yours and yours alone in those moments and you will never get that time back with that child. The calendar will quickly tick the days away and they will be too busy crawling and walking and running and playing to sit and rock and cuddle.
If you are a mom of a busy toddler who gets into everything and you feel you can barely keep up and you wish they would just get a bit older so they can play without getting into too much trouble.... embrace the wonder and excitement of their world at this phase in their life. Really take the time to see the interest and pure joy in their eyes as they unravel the toilet paper. Laugh with them in that moment.... don't freak out. I mean come on, you can always buy more toilet paper but you can't buy back that moment if you flip out and get mad at an innocent 18 month old.
If you are the mom of a sick child and you aren't sure you can go another sleepless night dealing with coughing or runny noses or the always fun stomach bug.. remember Jesus said "when you have done it unto one of the least of these, you have done it unto me"..... think about that.
Don't grow weary, grow in joy and peace as you embrace what is right in front of you. Don't wish for "better" days... these are the BEST days of your life!
