Sleeping arrangements for a 4 month old

[DorothyMantooth]

Sorry if this is in the wrong place!

DH and I currently live in a very small 1-bed apartment with DD (almost 4 months). Our bedroom is far too small for a cot, so until now DD has been in her moses basket. However, she's really too big for it now, and I'm trying to come up with an alternative sleeping solution for the next 2 months (we'll be moving to a 2-bed in September, where she'll have her own room with a cot).

We've been co-sleeping a bit recently (by accident) but I would prefer her to have her own space if possible, as I don't think our bed is really big enough for safe co-sleeping. Last night I ended up letting DD have my space in the bed and sleeping on the floor! We were thinking of hiring the NCT bednest but a friend's baby (smaller than DD) is almost out of her. Does anyone have any recommendations for alternative sleeping solutions for the next 2 months? I'm not keen to spend too much money as it's just a temporary solution, and it can't be too big as we just don't have the space at the moment.

Thanks!

Some of the cots in ikea are pretty narrow/small and inexpensive - we used a travel cot for a while but the ikea cot has a smaller footprint and the mattress is clearly much better. Depending on the size of your bed they can also be modified a bit to sit along side your bed with the side down using bungee cords and a towel (to push the mattress flush with yours) if you want to co sleep but have your own space
