Do you think my toddler has a speech delay?

Don't worry although it may seem as if everyone is better, 3-5 five word sentences is the average. I used to take care of children before and most of the three year old I met could speak only a little but had a little bit of problems with shapes and colors. The four year olds were better at that. If anything, maybe he is more of the artistic than analytical child and that is perfectly fine since most people think with either one side of the brain or the other. Maybe he will be more creative. :)
