Just want to share with you a story I heard, hope this could release your worry...
Once upon a time, there was a mother whose baby has no tooth at 1yr old, she asked the doctor whether this is a problem, the doctor replied: "Have you ever seen a kid without teeth?"
So, my answer is: "Don't worry, they will come soon"
If you are really worried, check with the nurse at the MCH when you visit for 1yr MMR vaccine. They should be able to give you professional advice
