P, B, M, are pretty much the first consonants, since they are formed with your lips and kids can see parents use them. Landon had an /M/ by 4 months, /b/ was maybe 19 months, and /p/ was just recently. His favorite thing right now is the vowel /ee/ with /p/ and /b/ so pee pee and bee bee/. I love it. I know how hard he has worked to get here!! Go Landon!!
