Some very good points here already but just add a bit for consideration.
Your parents are different to you and they behave differently to you.
I understand that those differences are hurting you. How to lessen the hurt is the key.
1) I agree change your counsellor.
2) Your DS is 3.
When we have children we Can (not must or should) Re-Do some of our own childhood. We can find gaps from our own early child experiences resurfacing. I would suggest you do some research around this and see if there is anything there that you can now take care of to meet any unmet Needs in your own development. If you think there is something in this for you I would strongly suggest finding a good therapist if you want to embark on work.
3) I agree with building your own sense of self worth. Have confidence in your own ability as a person and as a parent.
4) Look at ways you set yourself and others up to let you down AND then change that - fast.
5) Accept that you want 2 "Other People" ( your parents ) to relate to you in ways that work for you. I get that but ...
What's real is you have is 2 other people relating to you in ways that are the BEST ways they figured out to be/survive/ relate in the world. They didn't arrive at this time in their lives or your life with a perfect way of being your parents.
They are who they are doing the best they can with what life, their families, their pain, their fears, their worries, their hopes and sadness, their skills, their joys has given them to get through their life with. Same as the rest of us - you included OP.
Accept that they don't relate to 1) themselves the way you do 2) others the way you do 3) to you the way you want them to 4) the way you relate to your child.
I suspect - out of awareness - they are giving you the things in life they wanted and never got. The financial support, the Material things. Support to go to Uni, to have the weeding you had ( I understand your contributed to both) did your contribution make the feel it was a team effort or that their effort alone wasn't enough ??? Who knows.
6) Ask yourself, really consider, may be they feel uncomfortable with the your Emotional, Nurturing, Calm, Caring approach to parenting. Either because it's different to how they parented and they don't relate to you that way, they could feel judged and criticised
7) If you think you are being a "Good Enough" parent (good enough is often as good as it gets as a parent) then take any compliments (strokes) when you get them - we all need them sometimes.
8) Do Not go Hunting for strokes in places you already know you won't find them. You are only setting yourself and the "Other" up to fail. Change that and change it now.
9) Look at what they do try to do. I understand about the 'Boundary" you set around presents from your parents but have you considered that you are preventing them from showing you How they show Value ?
It may just be them giving you something that later gives them a stick to be you with, I can't call it but I think if you take the time to sort out the distinction you will be able to separate it out.
10) Their referring back to past financial/material things and wanting gratitude could be - only could be - more to do about them feeling "Not Good Enough" than it is about them wanting you to feel 'Small and Indebted". They are Your parents, you know their back history.
I don't know what the distinctions are, it will take work. Start with getting your view clearer, are they Narcissist ? Are they relating to you in the best way they know how ?
I get that their way does not work for you - it does not give you what you want from them - so stop asking them to be mountaineers and being hurt when they can't climb the mountain to get you what you want.
I get that you Do Not get what you want from your parents, you Don't get your Needs met. That is painful. Work out How can you get your Needs met? Work out from whom do you get your needs met?
Are your parents inherently Wrong in the way they relate to you ? Or is there way of relating Wrong for you? Well their way of relating and valuing is clearly Wrong for You. You are hurting and that is sad.
We can not change other people but we can change how we "Think" about those people and their behaviour. We can change how much Time and Energy we put into Thinking and Feeling about relationships and situations in our lives.
You have lots of opportunities in your relationship with your parents that you can change to make your life better.
Finally get a diary and go through how much of your Time you spend with your parent every day, week, month year. Then how much time you spend being hurt, angry, sad about How you think your parents are and then How much Time you spend finding out Who your parents really are.
Once you can see that written down you can CHOOSE what you do with Your Time, Thoughts, Energy, and Feelings.
Most importantly Keep yourself Safe, get yourself some good support, while you go through this trying time. Good Luck
