Hi, Thanks for answering so quickly!
When he left in December 2010, he picked her up from school Mon/Weds/Fri until I came home from work. I have always picked her up on Tues and my mum on Thurs. From August 2011 I got advice as he was wanting to keep her overnight and reluctantly I agreed to a Fri night, this worked well and got her used to her new environment from a young age. In the summer 2012 he moved his new family closer and reluctantly after taking advice, he requested a Weds night and I had to agree. He always wanted Mon night as well but I said it was a big adjustment and would review in the winter term which I did and said I was not prepared to change it as it had been working ok.
He has had her up to a maximum of 9 nights during the school holidays and I arrange with his mum and dad to have her on a Sat night every 3-4 months so he takes her to them and technically could stay with them as well. This has happened when there have been family birthdays/celebrations etc,
