We started with just a Moses basket (no cot). They are great for carting your baby around with you at home i.e. if you're lucky enough to get your baby to sleep at, say, 6:30pm, you then have the baby in the room with you while you have dinner, watch telly etc. Little babies sleep really soundly so you can still chat and make noise etc.
They are also good in the nighttime if you are having a rough night and want to leave one person in peace. For us, our DD's "bedroom" was our spare room and had an adult bed in it... meant one of us could easily decamp there with her if needed during the night, so we weren't both up with her for every feed etc. Likewise going downstairs to the sofa...
We had one that you could put on a stand, which was cool, and probably nice and safe so you're not tripping over it on the floor at night.
Moses baskets don't last that long because babies outgrow them, but they don't have to be expensive at all.
Starting with a Moses basket also means you can pick your cot when you're a couple of months in and know what your needs are.
For example, when DD got too big for her moses basket we actually picked a small cot on wheels to maintain some portability. We'd get her to sleep in her bedroom, then wheel her into our room when we went to bed (so she would be in with us during night). Made it easy to get her sleeping in her own room when we hit 6 months, because she was used to doing her bedtime routine in that room.
But some people might decide to do co sleeping or what have you instead. By the time you're ditching the Moses basket you probably have an idea of what sleep arrangements you want.
And congratulations! Hope you enjoy the rest of your pregnancy
