Speech

My son is going to be 11 months on the 25th and I'm a little concerned about his speech. He's not really saying anything besides "dada." Everything is still dada and I haven't heard any other sounds besides "eh" or other vowel sounds. He's reaching all other milestones wonderfully- he's walking, pointing, eating solids, sleeping well, etc. He can point to things when I ask, like "Where's the fan?" Or "Where's mama?" (If he's not distracted) He's a very busy little guy. I am constantly talking to him and naming things throughout the day, especially when he points to things. Is anyone else in the same boat? I know it's a little early to worry about speech yet. Thanks!!
