1yr old seperation issues

[Kaz52]

Help!
Any tips on dealing with separation issues in a 1yr old?
It started just when he was tired, I'd leave the room and he would scream.

Now it seems to be every time I even think about leaving the room he screams. Even if daddy has hold of him and I leave he screams.
Once calmed down he's fine until I leave again!

Starting to struggle now it's half term and my 4 1/2yr old would rather play upstairs than listen to the noise!

Is this something he will just grow out of?!
Any help in dealing with it in the meantime?

Making a noise is the only way a one year old can communicate. Imagine if it was you and you couldn't talk but wanted to convey the fact that you are frightened to someone who you loved a lot. Please be patient and it will be something he will grow out of.
Something has frightened him and so he needs as much reassurance as you can give him. The more you back off , the longer it will take for him to feel safe again.
The only alternative is to take no notice and let him scream. Personally I couldn't do such thing. They soon grow up and any patience and kindness you show to your children will be repaid in shed loads when they get older. If he keeps getting reassured, surely this will reassure him that you are not going to leave.
