Not feeling pregnant?

So I’m wonder if anyone who had a toddler with a new baby can offer advice. I have a 2 year old and I am just not feeling pregnant this time around. Like I honestly forget that I’m pregnant sometimes, I haven’t shared it on Facebook where I did right at 12 weeks with my daughter. When I was pregnant with her it’s all I thought about was being pregnant. Is it just because I am busy with a toddler? I worry that I’m not feeling attached enough to my baby or something. I do sometimes get feelings of guilt too like I didn’t have enough one on one time with my daughter before getting pregnant. Also I had a second trimester miscarriage with my first pregnancy, so I know that causes some guarding as well. So I don’t know if I’m looking for advice or just trying to get my feelings out. Thanks in advance
