B.K.
My son was easily frustrated like this as well. It's that in-between phase when they know what they want but they can't verbalize it & can't always make their little bodies do what they want it to. It wasn't popular when my kiddos were little, but I've read a lot about how much baby sign language can help bridge this gap. Something that did help when my son was little - although it certainly wasn't a quick fix - was I told him over & over when he got frustrated to ask for help. It wasn't a quick fix, but eventually learned to come ask me for help before he got so frustrated he started throwing things or crying. One more thing...if you find that there are particular toys that are frustrating him, I would put them up for a few months & try again later. Specifically, we had to put the Duplos away when my son was about 18 months old because he wanted to play with them but they wouldn't stay stacked the way he wanted them to & he would inevitably end up having a huge meltdown because of it. Hope some of these ideas help!!!
