We dont have a lot of battery operated stuff around here but we were given this mobile that attaches to a crib and it has a feature that shows a soft light show on the part that attaches to the crib.
We tried this thing and DD loves it! She will fall asleep all on her own after nursing when I place her in her bed and she watches it which is something I am happy about. The only thing is that the lights and music only play for a short time so we have to keep pressing the reset. Does anyone know of something like this that will play for a long time or just until turned off
