Same here!
DP and I are in a one bed flat. We'd been TTC for so long, we never thought it was going to happen, so we never thought to move to a bigger place in preparation.
We started looking for places when we found out I'm pregnant, but we're still struggling to find an area that meets both our requirements. I need good train access into central London for work. DP drives to and from work, so ideally he doesn't want to spend half his day driving and half his wages on petrol.
We've resigned ourselves to the fact that we will very likely still be in our one bed flat when baby arrives. We don't really want the added stress of house hunting while I'm pregnant.
We're having to move a chest of drawers out if the bedroom and into the living room in order to fit the cotbed into the bedroom.
We don't have masses of stuff, but over the past couple of weeks, we've started to clear out some bits here and there to make extra space. Unfortunately, we don't have loft space, but my mother does and she is happy for us to store some larger bits there (like our holiday suitcases).
It is what it is, and we will make do with the space we have as best as possible.
