Anytime I give mothering advice it is with some trepidation as I know that within 24 hours a child is going to humble me in that area. God is so good to keep me from becoming prideful.
Another concern is that you never know just how the advice will be received and understood. Years ago a dear sweet mom, expecting her second child, asked me how we handle more than one little one at Mass. I suggested using the stroller to contain them. At that time our parish had a large vestibule where we could see and hear Mass but not disturb those in church. So we parked the double stroller in the vestibule till we needed to leave with littles. It worked very well. After that conversation we never saw her little ones out of the stroller till they were nearly five.
A year or so later that same mom asked me when I started my children on cows milk. I rather flippantly replied, "When the crawler finds a sippy cup of milk left on the floor and they drink it." Poor thing was properly horrified and didn't ask my advice for a long time after that.
Recently she shared a concern and asked for my advice again. I suspect she has mellowed and gained confidence as all moms do. Maybe she thought my children don't appear to be turning out too badly. Hers are certainly turning out well, she and her husband are doing an excellent job! I need to go to her for advice! Though I will be considerate enough to advise her of the perils of advice giving first!
