Offer to watch her boy one night a week so her and her husband can spend some alone time together. Or ivite them over and cook dinner for them every now and again. Think thoughtful. If you see something while you are out, buy it for her. Like, if she's into scrapbooking and you see some cute stickers, grab them. Or bring her a cup of coffee from Tim Horton's when you pick up your son. Or maybe on a night she doesnt have plans, bring over a movie and some Ben and Jerry's for the two of you to have a mini girl's night. Hope I inspired some good ideas for you!
