I have a 7 month old baby girl and I'm 2 months pregnant. I'm a little worried about how much attention my 1st born will get, but i also know things have a way of working out.
It's a short window for babies. I kind of know how you feel but I haven't been sad about it. I try to live in the moment--spending time with my toddler and truly appreciating it. Also grandma rides in the backseat with him when we go out for a day. Pretty soon there will be 2 car seats back there & Gma won't fit so she is cherishing time as well.
I remember the day I found out I was expecting my surprise 2nd child. That night I knelt by my little boy in his toddler bed to do bedtime story, and wept. I wept because I knew "this" was never going to be the same. He was my sidekick and buddy, and now he would mever have just me ever again. I felt guilty that I was changing his life. BUT...when I saw what a wonderful brother he naturally became, how much he ADORED his baby, and how beneficial they were to each other as siblings, I saw what I didn't forsee in my pregnancy. Love within the family unit is amazing. It grows to fill all hearts and spaces.
I have 2 girls and a boy, my oldest 17 and youngest 11. I still miss when they were little and needed mommy. I don't think that will ever go away. But they do have to grow up and learn how to do things on their own. With my 17 y/o I sometimes worry if she is ready to go on her own in a year from now, but I also still miss her being little. I guess it's kind of a bittersweet feeling. But you and I both have a baby on the way, and when your baby gets here you will find yourself with plenty to keep you busy, including rocking her to sleep. Enjoy and take pride in your sons milestones, there will be many! :)
