I agree that it might not be the perfect place for you to find an answer to your question but will add my anecdote nonetheless. I am 32 and lots of my friends around started to have kids ~ 5 years. I can see that one of my friend has 3 kids that appear to be normal in every way. I have another friend who daughter is exceptionnaly advanced for her age (she speaks two languages already and started to speak earlier than the others kids). I have another friend whose kid started to speak pretty late (~ 4 years). So if you try and compare your kids with what a "normal kid" should be like, I think you will develop gray hair fairly soon :) The best thing to do is to talk to your pediatrician and see if there's an issue. Don't hesitate to talk to different doctors if you want different opinions but I know that most parents try and compare their kids with the other to see if theirs is "normal". I think your children will turn out to be just fine and I don't think they will have any sign of mental issue at all - you're just a scared parent and it's OK.
