We used the carrycot from our pram with our son when he was born, but only for naps. At night he slept in his cot. We lived in a small flat then, so we didn't have room for a moses basket. This time we're in a much bigger house and have room for one, so we'll be napping her in the moses basket during the day and having her sleep in a beside crib at night (I ended up pretty much cosleeping with my son, so the idea is that in the bedside crib she'll be at my side, but in her own safe space - I was always paranoid about my son getting hurt in our bed). My son outgrew his carrycot within the first two/three months. He was huge and I'm not expecting his sister to be much smaller. The bedside crib is a lot bigger than a moses basket though, so hopefully she'll sleep in that much longer than 2/3 months!
