My DD1 got her first tooth at 14 months. She cross cut and had them all within a couple of months. It was completely stress free as her sleep was already so well established. She would wake up in the morning and I would notice a new tooth when I lay her down to change her nappy! She is now 11 and has congenitally absent upper laterals, but I don't believe that had anything to do with being a later teether.
What are congenitally absent laterals??
