hey Dee ... Jesse has used a sleeping bag since he was 3 months old ... he sleeps very well in it .... i am convinced that is why he doesn't wake as much during the night because on occasions we didn't use it he would wake from being cold ....
Also, another question regarding the bags ... what do others dress the little ones in underneath .... i usually put Jesse in a body singlet is this enough or should he be in normal pj's under the bag ??
