as our little one is 10mo, i'm not as concerned about this as my lady is.
she is adamant that she is little ones mom and no one else is to ever have that title for him. or to be acting as little ones mom.
as little one is only 10mo. he's a little young
as my lady has other b/f's currently, her concern has been to have them recognize and get along with little one, but that's it.
everything sounds reasonable to me.
