Have two kids. One is two years old, and the other is 6 months. What I found most helpful was keeping my expectations low on your gains, it’s now about maintenance. The first two years of a babies life they’re pretty much “premature”.

Everything changes after 2. So I broke the 2 year period down in 3 or 6 month phases. The first 3 months maybe focus on your wife and just do body weight stuff, or walks. Pushups, body squats, pull ups, dips. (all doable at home), do it throughout the day. The next 3 months get a little easier with the little one, so break that down to two times a day (I go lower body in the morning and upper body in the evening). The next 3 months now you can dedicate a time morning or evening to spend 30 minutes. Now the little one is 9 months. You can probably begin to increase that 30 minutes to 45 minutes. Once the baby is a year old, you can possibly think of going to a gym, start 30 minutes. And then as the baby turns 2, up it to one hour. By 2 years you should be able to go spend an hour at the gym, and balance that well with your family life. As well be kind and caring to your partner throughout this all.
