Firstly how old is your child? And Also ist he/she is wanting contact and there are no other issues to consider...?
You need to word your letter with much fewer 'I's' and be more child focused and positive. Be matter of fact and less emotional ( I know you want to point out what a sh1t he has been, but it achieves nothing for your child). So perhaps something more like this....
I am writing with regard to your letter regarding contact with [child].
Both [Child] and myself are keen for contact to resume and for a regular pattern to be established.
As contact up till now has been sporadic and subject to short notice changes I propose we start with establishing regular and consistant contact first.
Once this is working well we can then look at increasing contact to include overnights.
I am sure you can appreciate that [child] will be more comfortable and reassured about staying overnight once a regular and consistant pattern for contact has been established.
To this end I propose the following contact on Saturdays from 9am to 6pm:
Saturday 6th November 9am - 6pm
Saturday 20th November 9am - 6pm
Saturday 4th December 9am - 6pm
Saturday 18th December 9am - 6pm
Once the fortnightly Saturday contacts are established, and [child] feels more confident that agreed contact will occur without last minute changes or cancellations, then we can look at moving to overnight contact.
In addition to the above Saturdays, I would suggest a midweek contact may be helpful to [child] in re-establishing and maintaining [his/her] relationship with you. This will have the added benefit of reducing the length of time between contact weekends for you both.
To this end I also propose the following Thursdays from 3am to 6pm. Please remember that you will need to make arrangements to collect [child] from school on these dates:
Thursday 25th November 2010
Thursday 16th December 2010
I can appreciate that Thursday may be less convienient for you due to work comitments. However, as a parent, school hours are something we both need to accomodate and so I hope you are able to accept this additional contact.
If you are able to establish this Thursday contact perhaps we could then move forward to a weekly midweek contact every Thursday after school once the new term starts in January 2011.
If Thursday is not convienient for you please advise if Wednesday is more suitable instead.
Regarding overnight contact I would suggest that the Christmas holidays would be a good time for this to happen should we all be happy with how contact is progessing prior to this.
As Thursday 23rd falls during school holidays we could continue the Thursday contact to include Thursday 23rd to be from 9am to 6pm. If this is convienient to you then we could potentially include an overnight on this contact visit should the previous contact go ahead as planned and [child] is happy with everything.
Assuming everything progress well we can then look at including overnights on the regular Saturday contact weekends from January 2011 onwards.
I also hope this will give you enough time to prepare a room for [child] in anticipation of overnights starting, should you require it.
Please let me have your response to this Saturday and Thursday contact proposal.
On a separate issue, I feel I must mention the introduction of your new partner to [child]. He appears confused about this situation and is not entirely sure who she is.
I still feel, as per our previous discussions, that it is essential for you rebuild your relationship with [child] before introducing any new situation to him.
I would therefore ask you to bear this in mind while we re-establishing your contact and build on [child's] relationship with you. Perhaps we could agree that you delay introducing your new partner for a few more weeks and then make it clear to [child] who she is while reassuring him of his relationship with you.
I appreciate this is a matter that you must decide upon yourself, but hope you can see things from [child's] point of view. Right now [he/she] needs consistency and reliablity in order to feel secure in [his/her] relationship with you and for contact to be built upon with the aim of moving to overnights.
You have also mentioned maintenance money in your letter. As this is an entirely separate issue I will be addressing that by separate cover.
I look forward to hearing from you confirming your agreement to the proposed Saturday and Thursday contact as detailed above.
