He will be 5 at the end of the month.
I have him alternate weekends from Friday pick up from school through to Monday morning drop off at school. I also have one night during the week. Tuesday/Wednesday alternating. School holidays are split equally.
No contact during the week apart from Skype on Tuesday after school. Alternate weekends from Friday afterschool probably about 1.5 hour drive back to mine from his school till 6pm Sunday if I drop him to her new place or 5pm at Paddington Station.
In the letter the only reason stated is moving to a bigger house.
