Something, and maybe when we have another baby it'll be the same way being more attached to the youngest. That being needed feeling. Other then being a mom idk what else I am. A wife with A pain in the ass medical issues lol.

I don't think it's favorites, I think your six year old is developing their own style/ personality. Their more independent. Also girls seem to have big personalities (mine twoteen omgsh!) they can definitely clash

I dont even know if its even favorites. My daughter has started stressing me out more and more every year, she's got an attitude problem, shes disrespectful, she just always bratty, where my son will come lay with me, come up and kiss me, or just come up and go hi mommy. But he does push for his independence a lot witch makes me sad. So idk if it even is favoites I think its just hes the baby and he still loves on me and lets me love on him, where my 6 year old is just a jerk all the time....

I don't think so. Some people think its not right to have favorites, but I think it's different for each mom. Some moms bond with all of their kids equally and some bond with one more than others.
My aunt is more partial to her 6 year old than her two year old, I think it really depends on their personalities. They may be your kids, but you're still different people who might not have compatible personalities. My mom and I don't, but we still spend time together and love each other, we can just go longer between visits than other parent/child relationships.
