When should you be concerned about articulation errors? Is your child saying wabbit for rabbit? Here are mean developmental norms for acquiring different consonant sounds:

2-3 years- p, b, d, m ,n, h, w

3-4 years- t, k, g, ng, f, y

4-5 years- v, s, z, sh, ch, j, l

5-6 years- th voice, zh, r

6-7 years- th voiceless

If your child is making errors with these sounds before the acquisition age do not worry! There is still time for your child to work out their errors and eventually accurately produce the sound. If your child is making errors with these sounds after the age of acquisition look into seeing a Speech Language Pathologist.
