Well, all three of my boys were full on during the day AND terrible sleepers. So lucky me got hit with the best of both worlds
For me, it's a no brainer, full on during the day but great sleepers, would be my pick. Without. A. Doubt.
Oh, and my reason, is because I haven't slept longer than a 2-3 hour (if I'm lucky!!) stretch in 5.5 years and counting. I would give anything to have had decent sleeps before having to deal with horrendous days. A.N.Y.T.H.I.N.G.
