Maybe that is a tease of a title, but Joshua has definitely been experimenting with the different sounds he can make as well as volume he can reach. David insists that "DADADADADA" is Joshua's first word. At this point, I would say it is more of his first syllable or vowel consonant cluster, but maybe he will place it with the correct person and then it will be his first word!
The picture doesn't have anything to do with this; it is Joshua looking cute while we practice sitting and learn Arabic all at the same time! Right now, Joshua is perfectly happy to not sit. Why learn to do it by himself when he gets attention and cuddles when we help him?!
