Co-sleeper vs camping cot vs both??

So, I'm planning on having the baby in our room for the first 2-3 months whereafter I plan on moving him to the nursery to sleep in his crib. (I read that from 3 months onwards baby should have a set sleeping space where they sleep during the night and at least one of their day sleeps).

I'd like something that can function as a co-sleeper. I think it will make it much easier in term of breastfeeding and such. Is it worth buying a co-sleeper for such a short amount of time? Should I just be buying a camping cot.

Seriously overthinking things here 🙈
