Congrats! I love how this makes you 'extra motivated'. Really shows the type of dad you will be and a great fatherly example your child is fortunate to have :) congrats again and all the best!
Really depends on your state of mind. If you have any tinge of burnout, I think it would be counterproductive to just jump right back in. But if you're excited and motivated, perhaps there's no need for such a large break.
