Dear A.C.
You are an amazing mom. We all lose things that are important to us all the time, especially as moms. We are doing the hardest and most important job in the world. If we did not lose things, then we must be doing something wrong :) But they are just things. You have a precious one in front of you. He will remember the hugs, the kisses, the smiles, the time, the love.
I agree that in time it may still turn up (happens to me all the time),
Thought: Why not sit down over the next month, and write in a journal for him all that you remember and that will be fine. Next, you can gather any pics others may have. Then you are done. Smile. You are doing a great job. The memories in your heart are more important.... And if you find the baby book, you will have both...
Now, on a personal note. My mom made me a nice baby book and picture albums. But she was and is not a nice person (to say the least). I do not have a relationship with her as an adult by choice. My point: today I would rather have a loving caring mother, than the baby book and pictures. They are fake to me. Does that make sense???? :)
Hope this helps.
Blessings, Jilly
