This is something I've been thinking about for a while as it can be hard to find Irish reviews of equipment and toys. So share your opinions everyone, we spend so long (or at least I did) in researching the things we buy so pass on that knowledge to those coming after you!
I'll start off:
Chicco Next 2 me crib
Pros:
Bought this when the baby was a couple of weeks old because the travel cot was just not working. I love it. I'm not breast feeding but the ability to just roll over and stick a hand in to soothe/calm or check if he's breathing is just wonderful. It's also a very portable travel cot (the straps are a bit awkward depending on the amount of room around your bed) and relatively tidy for transport, it fits on the floor of my backseat. It even comes with a handy travel bag. My son has reflux and this can be very easily and safely reclined for sleep. It's also nice and wide so baby has loads of space (which he loves). It is deliberately slightly lower than me so he can't roll into the bed accidentally.
Cons
Price. Honestly I have no other problems with it, it's been a huge success for us.
Advice:
From Internet research it is very possible to do this with your actual cot if you are careful. For example
