Experiences of others?

Hello everyone, I wasnt sure of many other places to look to ask about what I'm curious about when it comes to adoption for both the adopting parent(s) and adoptee as I dont have anyone in my family thats gone through the adoption process as either party except for 2 younger brothers from my father who I havent had contact with anyways since they were too little to remember me, and I unfortunately dont know much more than the circumstances they were given up in.

I'm (early 20s F) currently about 30-30.5 weeks pregnant, me and my boyfriend (also early 20s) found out quite late (around when I was 26 weeks). While we were initially set on adoption I have been having a hard time feeling more sure of that decision as I've started to grow attached to my baby (especially when I'm the one feeling him move around all the time and learning about the things that make him more excited or seeing/hearing him in all the ultrasounds).

As someone who doesnt have people to talk to about the adoption experience, I can't help but feel worried about certain things and was hoping others might be able to tell me about theirs?

We're looking at an open adoption, however I would like to be able to visit and spend time with my baby, but I'm just curious how that might feel for them? I want to be able to watch them grow up and learn about them, but would knowing about their adoption and spending time with me still feel weird for them? What's it like for people who have been in those types of situations? Is it better to not be involved in terms of starting to spend time with them when they're younger and letting them come to me instead? What have those who have been adopted felt about their experiences?

For adoptive and birth parents, what was that communication experience like for you? Was it easy? Hard? Is it still that way even as your child has gotten older whether they knew about their adoption when they were young or not? How have your conditions of your adoption been treated as time has gone by? What type of mental/emotional tolls or effects has it had on you?

I have a lot of curiosity and questions and my own worries when it comes to adoption, but I'm hoping to just gather the experiences of others people to help me gain insight to what I could maybe expect or help us decide whether adoption is truly the right choice.

Any insights or experiences besides what I've asked about would be amazing! Thank you so much in advance to anyone who takes their time to share with me
