Congrats!
The day my kids were born has to be the best 2 days of my life. A close second is when my 3yr old was able to explain to my 1 yr old son what SPS means. I would have never expected her to retain all the reef stuff I told her as she was fussing. Looking at the tank and softly talking to her always did the trick. I didn't know what to talk about except the tank. As for a diaper skimmer, the closest I could get was a canister filter, get your self a diaper genie
