I have not heard of ANY case where ALL babies teeth come through at once. They might be moving around as may daughters are. She has her bottom two and two front two ALMOST through. The others look like little WHITE BUDS but are not coming through only moving around.
From what i have heard, usually they come one at a time, sometimes two at a time... but usually not all at once.
Try to have a look on things about development on the net. I have never heard of a case where ALL the top ones come througha at once. Have u asked a paediatrcian???
