The next time you see a mom of young children, send her a smile and ask her how she's doing.
She could be a stay-at-home-mom who hasn't had time for herself yet feels alone and wishes someone could offer some help with her kids.
She could be a working mom who struggles to put a straight face while pleasing her boss and wonders how her sick child is doing at daycare.
She could be anything, but she certainly could use a smile. And a hug.
