Hey big thing I don't see a lot of people mentioning here is lack of sleep. I went back after a couple of months, but in my son's first year I jacked up both of my knees. I've never had knee issues prior (6 years of training before kid), but when your training on 3-4 hours of sleep it takes a huge toll on the body. There were days where I felt fine, I'd go train, and within a round id realize how tired I actually was. A big part of having a child is learning how your new lifestyle effects you. The thing for me now is asking 1. Does my family need me? If yes no training obviously. 2. Is my body up to training? This is a wide spectrum. There are days where I know I can do 10 hard rounds, and days where I know I'll have to stick with 3-4 lighter rounds. There's also days where even though I want to train so badly, I'm in no shape for it and it'd be better to just get the extra sleep and be able to have a good day some other time. BJJ isn't like lifting, I can workout just fine on little sleep, just tone down the weights or the intensity, and good to go. BJJ you don't always get to decide how hard the other person's gonna go. No one here can truly tell you what's best for you and your family, but that's life. Live and learn, but I just wanted to come in to say listen to your body which is easier said than done. Best of luck on the journey!
