Question for Moms with more than one baby!

Is it normal to kind of forget your pregnant?  I feel so out of tune with this one 😩. We have a 13 month old, a 9 year old, and we share my husbands beautiful 7 year old, so at times I have 3 kids and most times it's just the baby and our oldest.  But anywho, I just don't feel pregnant, I mean aside from like normal symptoms like morning sickness and fatigue, etc.  I just feel like with our 13 month I was so in tuned with the pregnancy from day 1!  But I find myself forgetting I'm pregnant with this little precious peanut! 😭
