My ds is coming up to 16 months and is a really happy, lovely boy. I'm worried though about his development. He's not got any words yet, which I'm sure is normal, but he doesn't point at anything or show me anything that he's playing with/can see from his pram. Is this normal? He's smily, giggly and loves cuddles and playtime so I think he's OK, but just need some reassurance that pointing is not a 'big thing' to focus on.
