perhaps your kids have their own issues and resons for barging in? As you say you've only just got hem back, perhaps right now their need to be close to you is overpowering for them..they have no room right now to allow you space....remember hey are still the children and seperation from a mother does a lot of damage..perhaps reasure them that your going to make a private phone call and will be back shortly and then suggest sitting down and talking together or something that doesn't remind them of abandoment which is how children view seperations? Ypu ca't really expect hem to fall into your routine immediately it will take lots of time and patience..
