I was just remembering some of my dad's wise words given to me when my son was a wee guy. There is always the peer pressure in regard to potty training, losing the soothers, walking vs crawling, and graduating from bottles to cups. Dad was a teacher and school principal for many years and his some of his favourite years were spent teaching Grade 1. This is what he told me:
"Susan, you need to relax about all these things. Children will learn as they are ready. In all my years of teaching Grade 1, I never once had a child arrive at school wearing diapers, sucking on a soother, or drinking from a bottle. All of them had given up crawling for walking. So don't worry."
It calmed me down and so I pass this on to whoever may need similar encouragement.
