10 month behind the times freaks out?!?

ok, so, my son this morning, is in his walker, eating some animal crackers, and my phone rings, so i step out side so i can hear, and he starts to SCREAM his person in charge off, he rams the door with the strider, throws his crackers all over the floor and just completely looses it! i was shocked! i own never seen my child act like that! what could own caused this?... he wasnt alone, someone was in the house next to him... in the same room so he knew they be there, what can i do about that?
i CANNOT have my child spazzing EVERYTIME i give up the house! im a working mom and im due to have another baby in 29 days,.
do u assume he might know the baby is coming and he is maybe feeling neglected?
i spend ALL free time next to him, he even occasionally sleep with me at nap time, maybe he is getting to attached?
i dont know what to do beside him,
has anyone else expierenced something like this so young? i thought that akward clingy stage be kinda far away for us.
Totally normal..my daughter have been doing that since 6 months..she's 18 months and still does it when she's cranky
That be kinda funny..I have a little girl whos 7 months..I cant do anything without her...If im playing near her on the bed..and i get up for a sec..she screams...if i put her in the playpen to travel to the bathroom..she screams..and even when she is with my fiance (her daddy) and i leave she scream on the top of her lungs until i return...glad to know im not the only one to go through it =)
Answers:    No that klingy stage is 9 mos to 2 years. Just when the baby knows that you are leaving or is not in attendance until they can really understand what you tell them and they can start to communicate with you. It will most credible get worse when the new baby comes, because this one is still to little to get the message.
Get your patience ready Mommy. You are going to need every once of it you can muster up.
When the unknown baby comes be sure to have 'special time' for big brother every day.
