I never buy for one of the girls without buying for the other....I love buying things for my Grandkids...I like to buy them things I couldn't afford for my children(we were in the Military for 30 years) Now we can afford it and I love to got shopping for them...I go a little over board at times...but I think it is because the girls live so far away...my son is in the AF and they are stationed in NC...His little girl lives in PA with her Mom...and we live way out in the Desert of Az
My son and the girls mothers don't mind that I go over board at times...they seem to understand. My 9 year old Grandson lives in Tucson...so we get to see him often...and I just love taking hiim shopping...He is an ADHD child and he lives with his Single Mom(Dad is not in their life at all) So we try real hard to be a big part of his upbringing...as does the rest of my family...My sisters and their husbands and their kids.
