You can hire them from places like Hire For Baby (I'm not sure if there are any branches near you). You could do a search of baby hire places near you on Google or the Yellow Pages. Otherwise look on eBay, you can pick them up pretty cheap sometimes. I used our Amby hammock up until DS1 was nearly 2! As long as your bub is safe and happy in there, you can use them for as long as you want. I swear it saved our lives! It was also great when going away because it packs up into a bag and DS1 had a familiar bed to sleep in wherever we went.

I'm glad to hear you had a better night last night!!
