The pinky is commonly the weakest & least dexterous. The advice manxcat gave you is absolutely correct: use it! Start getting it into the act as soon as possible. The only way to get better at any manual dexterity is repetitious practice until it becomes second nature.

I have a couple of tutorials that can help build finger strength & dexterity, in particular focusing on the pinky, but can apply to all fingers. These are not necessary, but I've used them for years to help students with this exact problem.
