I think you should wait until after the New Year before saying anything as before Christmas young parents are often so busy that tempers flare.
Sometime in February, I suggest you either invite all your children or if you prefer invite one child + partner at a time and say you have something you need to discuss.
First tell them you have rightly or wrongly a feeling that they are distancing themselves, so you would like to know whether you have hurt them quite unintentionally in some way. This way you are not accusing them so much as
sounding concerned. Tell them you miss seeing them and would like to be more in touch, but that you respect the fact that they have busy lives. Then see how you can progress from there.
I would quite frankly tell the son who makes plans to visit and then changes them, that this is annoying, as you have made preparations for a visit that does not take place. The older we get the more most of us need to be able to plan ahead, we are no longer up to running around at the last minute buying food or baking!
I would be equally frank with my daughter and tell her that I resent feeling that I have to take second place to her in-laws, because they are pushy, and she obviously either will not or cannot tell them that she is going to visit you, so she has no time to see them if they drop in , as she is half-way out the door to see you.
I'm sure you know how to put all this so as not to force your children onto the defensive, making things worse.
If you say and do nothing now, you are going to feel more and more resentful. I feel it is worth the effort to try and change things now - the longer you leave it, the more impossible it will become and the more unreasonable your reaction might appear to your children.
Tell them in the early spring that you expect them all for Christmas dinner next year, as they were with their in-laws this year. That is quite the done thing where I live, that young couples go to his parents one year and hers the following year, or invite his one year, and hers the year after.
Above all make it clear that you love and miss them - start by saying that.
If nothing changes, then stop lending them money, say you now longer can afford to do so.
