PC Unable to add a nursery room

[Kejt]

After 3 house upgrades and all room enlargements have been added I have no visible option to add nursery.Robin has no work now and ‘shop’, ‘construct farm buildings’ and ‘make house renovations’ options are visible but nursery is not. Do I need to unlock it somehow or is it a bug?

You should already have one? The second upgrade added two rooms north/up from the rest of the house. One of those rooms has a cradle in it. That is what you're looking for.

If you want to add the crib, that's under renovations.
