speech progress

For the longest time the only consonant sounds Ella will reliably make are "D" noises. You could get her to occasionally make "B" or "N" noises. She would even, through rarely, make "M" noises. Also, when you try to get her to purse her lips to create a concentrated stream of air (like you would to blow bubbles) she would only blow out with her mouth and throat wide open (as you do when you try to fog up glass).
The great progress is that she is making "B" noises much more frequently. Also, last night she repeatedly pursed her lips to blow a concentrated stream of air. We even got her to blow about 10 bubbles over a couse of 3-4 blows on the bubble wand.
