Hi E.,
I have used the Angel Care monitor for both of my children (my son, now 22 months old, and I'm still using it for my daughter, who is only 8 weeks.) Best thing ever, I tell you. It gives me such peace of mind, I can sleep better. Seriously, I've only had 3 false alarms over the last 2 years, and like a previous poster said, I'd much rather deal with a few false alarms than to regret not using this monitor. It really is a great thing. When your daughter is older, you have the option of turning the sleep sensor off and just using the sound portion (like I did with my son.)
Oh, by the way, you might be able to ALSO purchase a real cheap video monitor. My husband found one online when my son was an infant for $70. The video monitor cannot tell you if your child is breathing or not, but it's just nice and convenient because you can see that when your child cries in the middle of the night, if she is truly awake or not (some babies cry and make noises in their sleep, especially toddlers because they dream so much). I know there are several times when I hear my son start to cry that if i go in his room, he WILL wake up. But I can see on the video monitor if he's still actually sleeping or not, a ndthat determines if I have to go in and "rescue" him.
Here is the link to that Angel Care sleep monitor. I really would invest in it. It's expensive, but it has 2 parent receivers, and it's well worth the money...two years later and we are still using it...
