At what age did your DC learn to count to 10?
Mine has recently learned, and happily recites 1-10 and sometimes even 1-15, however he always forgets the number 8 - it's like it's just dropped out of his head, although when prompted, he knows 9 comes after 8.
He's only 23 months, so am not worried about it, just wondered at what age your DC learned, and if so, did they forget a certain number too?
