To not want my 13 yr old sister to babysit my 3.5mth old baby, its my dads girl and acts too grown up for her age, and she has text me saying if i want to go out sat night she will bsit,,,,my dad and stepmum's got a laid back approach,so i dont want them to think im been uptight, how do i say no politely? ...or am i been unreasonable to not want her too, but i just think 13 is too young to look after a baby and i would be worrying constantly about my baby, it would be different if my dad was there as well but its just her on her own wanting to
...help me find a way of saying no with out looking ungrateful...
