Baby after miscarriage

My baby girl is 13 weeks today. I'm over the moon happy that I have my baby girl. She wasn't my first pregnancy though. I miscarried my first baby in June of last year. Thankfully I got pregnant again within 3 months and obviously it was a successful pregnancy that time. Since having my little girl I haven't really thought about my first baby. It tore me apart when I lost him/her but I moved on from the loss when I got pregnant again (I'll never forget my first baby). My boyfriend yesterday asked me how often I think about our first baby and I answered honestly that I don't that often. Im just so caught up in enjoying my baby girl. But he told me he still thinks about it a lot and now I feel like I'm insensitive and didn't really love my first baby cause I don't think about him/her enough. Let me clarify as well that my boyfriend was by no means trying to make me feel bad or inadequate, it was just something that had been on his mind for a while. Well I guess pretty much what my post is for is to see how other moms who just had their rainbow babies deal with or remember their angel babies and to get reassurance that I'm not a horrible mommy cause I'm enjoying the heck out of my baby I have here with me.
