Work on strengthening your feet, ankles, and legs. Work on building those muscles every day. But I should also tell you that typically, one doesn’t go en pointe a month or two after starting. You need a certain level of training in addition to the proper muscle strength before starting pointe training. So keep at it, work hard, and be patient. They will come when your teacher feels you are ready to handle them. But for now, focus on learning as much as you can flat. Pointe will come later.
I hope this was helpful. If you have any further questions, don’t be shy to ask. Keep calm and dance on. =))
