DD is a little over 2 weeks old and starting to be awake for longer but I don't really know what to do with her! We talk to her, sing sometimes snd I wave around a rattle to get her attention. We also do a lil tummy time here & there. Is it too early for the playmat? Am I supposed to do anything else to entertain her or help her develop? Or it's ok to just let her stare into space sometimes?
