Hi,
There are two ways round this, one is via
mediation and one is via court.
Perhaps
your initial position should be to try and secure every other weekend,
since there seems to be no objection to you having your son on
some weekends. If midweek continues to be a sticking point you could try
the approach of extending the weekend to cover pickup from
school on Friday to drop off on Monday
morning. You could also suggest seeing your son midweek but not overnight.
Which ever way you go, have a very clear idea on what you are going
to ask for, so alternate Christmas / Easter, half of school holidays,
family events (your birthday etc)
