Paano nyo ihahandle para walang favorite lolo/lola ang anak nyo and same lang ang treatment nya sa parents and inlaws nyo?

From what I noticed, madalas nagiging favorite ang panganay since sila ang unang nagiging ka close ng grandparents. What I did when I had my second baby, I see to it that she also spends time (separately) with her grannies. Eventually, napamahal na din sa knila ng husto ung pangalawa and they would always look for both babies already.
