Given that you cannot play loudly due to the baby, I think you will find the MilleniaOnes to be a good fit to your situation. Smaller speakers do have limited bass response, so be sure you get a sub that will fit in the front of the room, near the speakers (have multiple placement options here, as getting good bass response in a room can sometimes be challenging). In addition, be sure the sub has output to about 150 Hz on the high side (in order to meet the frequency response of the small speakers without leaving a hole). Then, extension to 35 Hz on the low end at a minimum (the closer to 20 Hz you can get, the better, but the 150 is more important).
As to the sub, I'm thinking that the SVS SB-1000 would be a good option for you. Small in size, with good output to 24Hz on the low end, but has extended response on the high end, up to 250 Hz. I'm thinking that this may benefit you when setting the crossover frequency, and perhaps give you more options in that area (crossover frequency is important in getting seamless sound from the sats/sub). If the price is a bit much, look for one used. SVS has a following in Canada, so there's a good chance you may be able to find one not too far from you.
