I've read a few threads on here where sisters are warring or have deep seated issues with each other that have stemmed from childhood.
If you have a lovely relationship with your sister, was it because of your parents and if yes what did they do.
Im not particularly close to my eldest sister (only sibling I have) as I feel my mum babies her and expects me to be the responsible one. Also my sister has no filter and often says very unkind things, and my parents have no problem with this- as a result I feel like the odd one out and dont particularly like being in her company.
I have 3 little girls who I love to bits and generally they play and are loving to each other. It would pain me so much if they were not close as adults.
