Leaving baby for multiple weeks

I would like to train as a pilot but in order for me to do so I have to attend a 10 week physical training course away from home (can’t bring any family with me). My baby is due in March and I’m thinking to start the training in September so when baby is 6 months old. I plan on leaving her/him with her daddy during this time. The thought of leaving my baby for that long is heartbreaking. This will be my first baby. But it’s important I do this for myself and my child to give us a better future. Does anyone have experience with leaving their baby for a long period of time? Could it traumatise them? Will they forget about me? Am I a bad mother for doing this? Or will everything be okay??🥺
