DS1 is 13MO and is a very loud boy. Most of the time it is just while playing so even if he is loud it doesnt bother me, he's a kid and I want him to express himself. My problem is when they turn to angry screams directed at me or DH. I have tried saying "No" or "Don't yell at mommy" firmly but that doesn't usually help and I think he is too small to understand time outs. I try to find out what it is he wants, food, diaper change, attention etc. I had a baby a few weeks ago but the screaming started before then and we haven't had any issues with jealousy as long as I am proactive about including him when I a nursing DS2. I have a feeling he is really just trying to communicate a need like nursing or he's hungry, but I have no idea of where to look for good baby signing materials and am wondering if is he too old to learn baby signs? Anyway, any advice about how to deal with this would be appreciated. Thanks!
I also should add that he has started talking and responding to us when we ask him questions but it just sounds like gibberish to us. That is what makes me think he is trying to tell me something but I just don't know what it is.
