Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first.
For clarity - how do you wish to share the care of the child with him?
I agree about the routine!
So do you mean he would have the child Monday to Friday and you would have the child at the weekend?
I have to ask - do you not wish to have weekends with your child at all?
So what you would like would be that he has the child from Friday to Monday alternate weekends.
Would you agree to him having Thursday nights as well so that the siblings spend time together?
Please do not worry about the threats that he is making.
There is ample evidence that 50/50 shared care for small children is not appropriate
and the Penelope Leach book entitled "Family Breakdown" also covers this
An offer of every Thursday plus alternate weekends gives a 5/9 day split and when the child is older then an extra night a week will make it 50/50 - but that is a long way in the futire when the child is well settled in all his environments
You should try and discuss this with him using Family Mediation
If that fails then simply tell him what the pattern will be.
If he refuses to return the child to your care then you can make an urgent applictaion to the court
Please ask if you need further details
I am sure you are right - but if he goes to court they are more likely to support you than him!
If it was a gift then it is yours no matter what
