As it is getting colder out, I am debating whether or not to change up LO's sleep "uniform." He has always slept in "appopriate" weight pajamas and in a lighter A&A sleepsack. I know that he is old enough now to sleep with a blanket (he's 12 months old) but I am still a bit skeptical, not to mention that he is a little wiggle worm and moves all around the crib at night!
Should I just move him into a thicker sleepsack? If so, can you recommend one?
