Is my house big enough to raise a family?

FTM here with some pre-baby anxiety.

Myself and my husband have bought our first home together - a 3 bed detached. We’re almost at the point of signing contracts and my anxiety has ramped up about it not being big enough. I originally wanted a four bed, but the area we’ve bought in is a little more expensive than other places we looked at so we ended up with a 3 bed.

Our first child is due in July and ideally we’ll have a second baby in a few more years. What do you think?
