Congrats on the newborn. My wife and I had a daughter just 8 weeks ago. Once you get past the first few weeks at home and can settle into a routine then you should be able to get your diet and exercise back in order.
In the past 8 weeks my diet hasn’t changed. I’ve managed to stay pretty strict with myself as far as thats concerned. The workouts did suffer though. I took the first two weeks off while my wife and I got the baby into a routine. Once I did go back it wasn’t easy. Lack of sleep due to nightly feedings has left my energy level lacking by the time the end of the day rolls around and I’m hitting the gym. I found that my workouts were ok at the start, but my energy level dropped quickly during the workout.
I just recently took another week off from the gym to try and get my energy back. It seems to have worked for me too. Last week I started Ian King’s Super Strength and Limping programs. Although I’m getting my ass kicked in the gym now my energy level has stayed consistent throughout the whole workout.
The big change that I made at home though was that my wife and I take turns with the nightly feedings. She does them on the night going into a workout day for me and I do them on the off days. She’s know been cleared to head back to the gym. She’ll be going on my off days so the feeding schedule we’ve set up will work to her advantage as well.
