I put this under sleep, but I think it's more than just sleep. Has anyone else noticed a 2-day type of cycle for their infant? It seems like for 2 days LMW sleeps well (1-3 hour naps! No night wakings!) and eats well. Then for 2 days her sleep is crap. Our nanny mentioned that it's common for babies to have 2 day cycles of sleeping well and poorly. Now that we have the fancy graphs on Baby Connect I can clearly see a cycle! In the "total sleep" graph, it literally goes up and down in a wave... up for 2 days, down for 2 days.
