Ever "too" much?

About 1/2 an hour ago I got off the phone with M, Ty's birth mom. She had called earlier today, and we were at the hospital for DH follow up appointments so I let it go to voicemail. I honestly thought she was just calling to tell us she had gotten the pictures and letter we sent, and I sort of forgot. So earlier tonight I listen to the message, and she sounds kind of out of sorts and says she is just calling to make sure everything with Ty is "ok". I realize that she HASN'T gotten the pictures, and maybe since it took me longer than I would have wanted to send them (cause hubby was sick) that maybe she's starting to wonder if I'm really going to at all. I knew she had a lot going on, and she was planning to use some of the pictures when she told her family about Tyler, and her pregnancy and Ty's adoption. I called her back right away, and she sounded completely different, and was very happy and relaxed (her usual self) and said she HAD gotten the pictures, after she left the message. She was thrilled with them, couldn't believe how many we sent (about 25), and relayed to me how everything had gone when she told her family (after she got the pictures)...it went well and her family was very supportive. It was a little harder with her children, but it sounds like she has scheduled all the counseling they need right now. She also asked me if Ty's older sister could write to us (she's 6) and I said of course! She went on and on and on about the pictures and she just sounded so relieved and happy and was going through them again as we spoke. Said she couldn't wait to put them in the huge album we left with her before we came home. So I told her I was sorry it took so long, and asked if it was okay if I had Walgreen's (where we get our prints done) send the pictures right to her house, so there wasn't the week or so lag while I wrote a letter (since we talk on the phone anyway) and then got to the post office to mail them. She said it was okay, and was really happy...even offered to walk over to her closest Walgreens to pick them up if she needed to. Anyway we got off the phone and I went on right away and ordered about 20 more new pictures we've taken and had them sent. The pictures seem to bring her so much joy, I would love to order her pictures every week or every other week while he's little and changing so much. It's only about $4 to send her 20 pictures! I was just wondering if that would get over whelming for her? Is that too much? Is there ever too much? Regarding calls...she usually calls me and I always make it very clear how happy I am to talk with her, and our chats are very easy going. I don't ever want her to feel like she's bothering me, but with 3 kids under 6 at home, I know she's busy, and till today, she couldn't talk about Ty in front of them anyway...should I also call her now? I can't wait till she gets e-mail! She did ask today if we were coming back to finalize in Missouri, and we aren't, which sounded like it disappointed her We didn't agree to any visits (it wasn't even discusses), but neither DH or I would be against it, maybe in the fall after we finalize I think. I would actually like to go when we wouldn't have any legal stuff to deal with, so it could be more relaxed without that additional emotional element. I guess I just never could have imagined having this amazing woman and family in our lives in this way. She calls us Ty's Mommy and Daddy, and refers to herself as Ty's "M"...even the birth father, R shouted hello to us when I first called her back. I guess I don't know how to get it all down to her on paper. I have a very hard time even expressing to her on the phone how we appreciate her choice (she actually went to get an abortion, and things lined up in a way, she felt indicated Ty was meant to live) I don't even really know if that's something that a birth mother wants to hear? The appreciation etc? I told her today what a blessing Ty was for us, and our family, and that I would never be able to express that to her enough. But maybe she just wants to hear about the Ty, and his accompishments? I also love asking her about his siblings, since it seems like they have all been very easy going babies (as is Ty), and they are very similar. Anyway, this was long...I guess I just want some guidance, and an idea about how "much" and "what" I can do for her... I asked her for a family picture of them, and she said they had one and would send it out "In the first minute of tomorrow"...she's so cute ;)
