Query: Had 2 and both broke in less than 6 months

I got two for my new twins. Both stopped working in the first six months. Those nights were disasters. Poor manufacturing. Time to splurge on a better model since clearly this isn't as good as it used to be. While it was working, we loved it. 5 and 6 months is just not an acceptable lifespan.
