I'm looking at both these things on Aden+Anais (I'm a little bit in love with this website to be honest!). Do you swaddle them and then put them in a sleeping bag or is it an either/or thing?? I'm completely confused. I miss planning on using a side cot such as the Next 2 Me, and I already have a Sleepyhead. I'm just lost as to what bedding to use! Baby is due in October so will be little over winter.
