LOVE the Nap Nanny. My little one had horrible reflux and this seat was perfect for her to sleep in. I highly recommend it! Especially for babies who are having trouble sleeping through the night! Most amazing product that I've found!
Hi..
An infant safety seat, also known as a child safety seat, a child restraint system, a restraint car seat, and, ambiguously, commonly known as a car seat, is a restraint which is secured to the seat of an automobile equipped with safety harnesses to hold an infant or small stature people in the event of a car crash.
A car seat is one piece of equipment you really need soon after your baby is bornYou can carry your baby in and out of the car without disturbing her too much. But, when taking a seat in and out of a car, always take the time to ensure the seat is properly fitted when you put it back in.
Some infant car seats can also be used as a rocking chair at home.
If your car seat is part of a travel system, you can fit it straight onto your baby's pushchair or pram
You can buy them at Babeez World it's a one stop online shop for Babeez and mom's .
My child loved the swing it seemed to really relax him he would go to sleep in ALL the time. It was the fisher price swing and seat. It was an amazing device 
A baby swig that mimics a car ride is literally the best thing ever, so if you can fidn something like the Mamaroo which does everything you’ll have every kind of motion and it’ll serve as a swing, bouncer and seat all in one! There are a few on this site http://kiddie-stuff.com/swings/ but I’m sure there are many elsewhere too! Good luck
