Hey I need some advice in the end of 2017 I met a new fella he has full custody of his daughter and I have two girls from a previous relationship shortly after we got together I fell pregnant with our son. my eldest daughter's and son's birthdays are 8 days apart and the other two girls birthdays are 11 days apart. His extended family such as nan and Aunt and uncle seem to think that its OK to just get the kids biologically related to my partner birthday presents but not the other two. Is it reasonable for me to be upset and angry that my two girls are left out because they aren't biologically related?
