Childfree woman and I are dating, but I have a child from previous relationship. Advice?

So I have been seeing a woman, 27, and things are going really well. She's intelligent, kind, organized, and a doer. She's the whole package. I'm excited about this relationship and I feel a good vibe about it. So, I do have a child (5) from my last relationship. He's sweet, well behaved, and fun. We share him, but I have him 7 nights a week. My previous relationship did not work out, and I have been very selective since then. I dated a woman last year and things were going well, and she said she was ok with a child, but once my child visited, she was done. I don't want this to happen again, so I was hesitant to bring it up again. Sometimes I feel like it's a filter, and its tough to date without the child being an issue. <br><br>I'm a doer as well, and I took my child to some of the classes I take. My new girlfriend attended the same classes as me. We met, clicked, and the relationship started. So, we are getting more serious, but I haven't told her about my child yet. I haven't had a sleepover at my house yet, and I haven't shared my child yet. I want to, but the last time it didn't work out so well. So I'm risking the relationship. I really like her. What can I do?
