A little background info first.

DH and I have recently separated.

In the past I have worked full time and also been in charge of doctors appointments, dentists, specialist appointments for older child who has ADHD. Taken time off work to attend appointments, stressed about meds and worked hard to get a good med for him that works well. I have also been the one who is responsible for making sure child takes meds before school everyday. I have vested a lot of time and energy into this process.

I have also been the one who has had "the little chats" from the teachers when things have been going bad at school, meds need to be adjusted, not working etc, issues that he is having.

So story today is:
This weeks is the first week of our split week parenting. EXDH on his first day today with the children forgets the meds and sends child to school unmedicated.

WTF. He has a container that will go back and forwards between houses and the last thing we spoke about last night was his meds and how important it was that we dont forget them.

He said to me "Shit happens" yeap shit happens all right. I am pretty angry.

I would be angry too. My DS has diabetes, so having his meds is vital. Can you text ex to remind him to do the meds in the morning? Would that work?

I would be angry too louise!!

But on the other hand i also understand it'll be a big adjustment for Dex. He hopefully feels like shit about it (even if he doesn't sound that way to you)
I would probably "let it slide" (but still be angry about it you TOTALLY have a right too!) this time and If he doesn't start remembering then you need to start questioning whether or not DS should be going there for the night.

I would also Consider getting DS one of those watches with alarms, so you can set an alarm on it to remind him about medication. This means at dads house thereis that reminders without you getting the "nagging EX" texting all the time to do the medication!

Yes I am giving him some slack as it is a big adjustment for him having to do the full parenting of the boys for three nights, two days. He also has to make school lunches which he has never had the responsibility for so its all a big learning curve.

I am going to ring tomorrow morning just before he leaves for school to make sure son has taken meds and do this for a while until the habit is ingrained and until he gets sick of me reminding him.

I did suggest he put a reminder in his phone, he was not sure about that.

I am sure he won't forget tomorrow.

He cant forget, it is really important.

I know it's not the school's responsibility, but can you arrange for your DS to have his meds when he gets to school? Maybe he could go past to the office before going to class. If his behaviour is a problem at school when he's not medicated, his teacher may have more of a vested interest than your ex in making sure the medication is taken. You could perhaps organise a container with compartments with the day of the week on them (I've seen these in the $2 style shops) so noone can forget whether he's already taken the medication or not.

I hope the arrangement you have has been working out these past 2 weeks.

I was going to say thaat if it should continue, ask about him being able to be medicated first thing at school - I have certainly experienced that with kids at schools I have taught at.
