We have the safe n sound meridien & were happy to use that from birth but when DD was about only 1 week old we went & purchased a capsule mainly for the convenience of leaving DD undisturbed while getting in & out of the car as it was a bit of a pain while she was tiny getting her in & out of the rearward facing carseat. It was also great having her rugged up in the capsule from before we left the house (especially if going out at night) & not needing to worry about blankets coming off etc as she was tucked in nicely.
I also agree that I think it is a safer option & I've heard it's not too expensive to hire so maybe look into what it will cost??

I highly recommend my safe n sound meridien, we still use it now & DD has just turned 3. Once our next bubs grows out of the capsule he will be using DD's carseat & she will go into her safe n sound booster we already have for her.
I love the way the side protection is a) there in the first plae & b) grows with your child up until approx 4 yrs! My DD is tall & it's still got room to grow with her.

I think car seats / capsules are one of the most important things to make sure the safety standards are high as its not only your driving that could cause an accident it's the people around you on the road.

I think it shows great parenting asking this question about recommendations on car seats as it shows you know the importance of the safety & your thinking entirely of your baby.

Good luck choosing, I hope I've helped
