No we did not use mediation. Initially my wide said 50/50 re: custody when she ended the relationship. Then she insisted on 4 nights a week which went along to but made it clear for the record I was not in agreement with it. When we first moved to our own houses 7/8 weeks ago, all was fine, I would call our son every morning when he was with her and vice versa.
However over the last 3 weekends when he has been with me I have noticed she'll call him once or twice over a 3/4 day period and thats it...which is fine, thats her choice, but over the last few days when I have been calling to speak to our son (either morning or evening) the phone will ring out and I'd get a text saying, 'he went to bed as he was tired' which I know is an excuse. The point is can she refuse to take calls from me when I want to speak to him...and if so can she stop me buying him a phone?
Generally speaking our relationship is an amicable one (though she does have a very short fuse) hence me checking with yourselves before I confront the situation.
