Liquid can work too.
Coq10 is fine for hubby, it's just more that it's expensive so if you aren't planning to TTC for sure for a while, it might be something to hold off on.
I agree with your assessment on the Omega 3, maybe even just once a week would be enough since you're still nursing. Err on the side of a lower dose.
When you're swaying blue it's all good to be a control freak, LOL! Good luck and blue dust headed your way!!
