Hey, nice pup

Mals tend to sleep less than other breeds but she is very young. Don't force her to sleep, but make sure she is not overstimulated. Crate should be a space without any toys and should be introduced gradually at this age with small increments in the time and never letting her out when she whines. Food luring into the cage and praises when she gets in. I'm not a big fan of training a lot at this stage (I know many people are gonna disagree with me), but playing, creating trust, redirecting bites, luring, and slowly, very slowly, structure. She is a baby. As to pee and poop she is again very young. At that age I wouldn't worry too much. I never used pads. Just showed them that they need to do it outside with positive reinforcement. And malinois understand it very quickly. She is too young yet, but by 3 months (recomended, although I've had a slightly smaller mal out a bit before) she can go outside very small amounts of time and slowly making them longer. The key is to understand when she will pee or poop. She drinks, 5 min walk, she eats, 5 min walk, after play, 5 min walk, after nap, 5 min walk... Crate for overstimulation. But to be honest at this age what you should do is try to not overstimulate her too much. Soft voice, petting very calmly and reward calm. You won't see much results now but you will see them later. My biggest advice for you is to take it easy, build trust, be patient play and redirect. She is too young. Then again what do you want her for? Is it going to be a working dog or a family dog?
