I dont want any of you to be offended but I have to point out that capsules are not designed for carrying bubs around or having bubs sleep in them at a house, yours or friends etc

The base is curved and this curves baby its not natural or good for their spine
This is true, but they tell you not to leave them in the capsule for any longer than 3 hours. Usually the baby will wake in 2 or so for a feed anyway.

I think its a great idea and I am going to hire one from our council. However before our trip to Sydney Oct/Nov I will buy a safe n sound one.
