I could never boast about my children’s walking, either. Son 1 was 18 months, son 2 was 15 months and my daughter was 16 months. Apparently, I was 17 months and my grandmother, who was still alive at the, told me that my mother was 17 months, too. Added to this, my mother-in-law told me my husband was 17 months, too. It really doesn’t matter - they all get there in the end. All my children had small feet and I wondered if that had an impact - especially my daughter, who was short, pump and still in 3-6 months pram shoes. As an adult, she is still fairly short, a size 6-8 and wears size 2 shoes.
