DS is nearly 4. His language skills are good and his vocab is excellent (I think!!) but he doesn't pronounce 'L' correctly and I am beginning to worry that this should hgave resolved itself by now. He can say 'L' if it is a middle letter eg doll but if it is at the start of the word he tends to pronounce it as an 'r'. Should I be worried? Do you think I should take him to see a speech therapist? I don't want him to get a complex about it...any advice appreciated - thanks.
