Ok so Stephany will be 3 mos old sept 6th. The last few days, well for about a week now, she has been sleeping 5-8 hrs at a time. Plus sleeping thru the night. I'm not concerned about her sleeping thru the night as she has been doing that since she was a month and a half, but she is usually up most of the day until a week ago. Is that something to worry about? It probably is nothing but being a new mom, I am not used to any of this. Could it be a sign of becoming sick? Or maybe a "growth spurt? Like today, she was at my sisters house and when I went to go. Pick her up after work around 230 she was asleep and my sister said she had been sleeping since 130 it is now 8 pm and she only woke up when I changed her diaper and then immidiatly passed out.
