Christmas - we made it routine that we have dss from Boxing day, ex has him Xmas day.
Last year, we had him from the end of school until Christmas Eve, she was due to pick him up at 9am. She arrived about 3pm. We'd not been able to do anything all day, not knowing what she was doing and she wasn't answering texts etc. Poor kid, just waiting for her on Christmas Eve!
Then she texted dp at 8.30am Boxing Day to say 'don't forget you're picking him up at 9am today' - sorry but she's a bitch. (it was supposed to be 9.30am anyway, not that we care about half an hour) We then had him til after new year.
Anyway, that means we've never had a CD, but does mean we've had routine which dss has been able to understand and anticipate.
This year however, he is older so the routine part isn't important any more and we have made a bid to have him from end of school to 28th, and she has not objected.
My only advice to those starting out is try not to plan too rigidly, don't emotionally commit to certain plans or ideas, try not to get het up when some other woman seems to have more control over your life than you do.....
So, this coming weekend is our w/e with dss. We had an extra one last weekend due to having a party (see above) and we would like him 21st/22nd for more parties, this time we are invitees.
I suggested to dp that we ask dm to swap for this weekend else she won't have him all of Nov. Plus I'd like to go to my sister's - dss can come but he might find it a bit dull, and he has a club on Sat he won't want to miss. Anyway, after ages nagging/reminding dp, he eventually texted ex on Monday. He texted "do you have dss this weekend" to which she replied [quite rightly] 'no, it's your normal weekend'.
So, I asked why he hadn't asked her what we needed to know - can we swap 14th w/e for 21st w/e? He said meaning gets lost in the nuance of texting. Um......
So, now he has arranged for dss to stay with a friend on 14th, so he still won't be with dm, and she has agreed we can have him 21st/22nd - so, as I predicted, she won't see him any weekend in Nov. It really just beggars belief. We already have him 70% of the time on our 'normal' times anyway. And dp pays maintenance (and I have asked him to pay more into our joint account as our grocery bills have gone up due to having dss with us more, so he is paying twice!).
