Yep definitely worth it.
Although mine was a gift, to do over again I would have bought one.
It made the first few weeks so much easier with the feeding every 3-4 hours. I think it was less disruptive for him as i didnt have to wait to hear him cry in the other room, turn any lights on to get up to him, and for me I didnt have to find warm clothes or freeze my butt off. He's still using it and we will continue to for a while yet. After that I think I might get a snugglebed so he can cosleep with us.
