Hi all. Thanks for your responses. It’s good to hear that they are genuinely looking out for him and not trying to spite my partner. It’s easy to doubt them because they’ve been difficult and argumentative before.
My partner worries about the maintenance as he pays to Mum who doesn’t appear to be around much, or at least around as much as Grandma. They have had difficulty with money in the past during their relationship/split with Mum trying to take my partner’s money that belonged to him - hence the worry that she just wants extra money. All three of them have parental responsibility, but Grandma looks after him the most as mum is often unwell.
We try to have a very similar routine (especially nighttime) to what he has at home, and make sure to align this if they make any changes. His bedroom is laid out almost exactly the same with the same pre-bed time routine - he even takes us up to bed when he is ready. The rest of the days are a very usual routine for him which he seems to cope with. I understand he might be masking some times, I did not think to consider this. We have witnessed a few extreme moments of distress/meltdowns which hopefully means he is able to not mask all the time. He genuinely seems happy with us and gets upset if he needs to, mainly about his stomach.
My partner tries to get more information about his child and school/medical information but he isn’t told much by Grandma and once rang up his school to ask about him as was met with angry messages from Mum telling him not to do anything like that. He would be more involved if he could, but they simply don’t give him that option. Even if he had a say in schools etc, they would not consider his choice.
We did use to see him every Saturday throughout the day but did drive him to our home and back. If we didn’t have overnights maybe doing something close to home is better for him, but it still means driving quite a bit in one day.
I understand that overnights might not be in his best interest just yet, my partner just doesn’t want to lose them as he thinks it’s important to have that contact with him and his son, especially with the settled side we see of him.
As for food/diet, he is not a picky child at all and eats whatever is given to him (even tries to get other people’s food) so for constipation it seems more stress related/if he holds it in. But he has a particular way to let himself have a poo which he seems not to hold in and does it when he needs (apart from lately when he can’t physically do so). He is more in pain from it not coming out.
From my side, I spend time with the child because I love him and he loves me also (we do have a lovely bond - he often comes to me over anyone else). I do tend to not be there all the time to allow my partner to spend time with his family as well with his son. I am there when it’s just my partner and his son but not always there when his whole family is.
We obviously want him to have the best life and care possible and want to contribute to that as best we could, we are just unsure what is best and how to work it.
Thank you for your advice and information. I need to do more learning on this topic.
PS sorry if I have done anything wrong, I am new to this site
