Im so sorry this is happening to you.
I dont really know what to say as i have never dealt with social services but it seems to me that they are not been fair to you.
I know they will say you are not their concern but they should care about your son and the fact it is affecting him, not to mention the effect it must be having on your daughter to not see her mummy. They are supposed to look after your children and i feel they are not doing so by not ensuring regular contact.
love cheryl xx
