Like many things that are inevitable, things get easier when you relax into them, go along with it, and motivate yourself to find solutions. The world is a difficult place for trans people at the moment, but don't let that spoil your time with your child. Explore your options together, support and love each other, get the help you need for you and your trans child by hook or by crook.
A trans child that is believed and supported in their gender identity, both by their families and the professionals in place to help them, will flourish.
