Сначало можешь сказать кто у тебя есть в семье, а потом: my dads name's ..., my mom's ..., my sister's, my brother's и так далее. We have birthdays in different times, i mean months, the difference is about 3 or 4 months(или not huge/big), so my birthday is on (e.g. 4 of october), my dads is 30 of january и т.д.
