These are some really cool updates. I especially like the updates on the baby. @CookieBaah a lot of guys quit the gym in that first six months or that first year after they have a baby. You're showing how it's done, how you can manage everything.
Diet soda doesn't even taste good. I'm not sure why people drink it. Maybe switch to some good quality raw fruit juice instead. That would be healthier for you.
It's pretty normal to not gain in a linear fashion. Your body can't keep up with how fast you're getting stronger so back off a little bit and then you can come back stronger.
