@jpajari Until we know just when to expect the EP, which may be hinted at in the Live Stream, (we never really know), it might not be released right away. It might come out later in the year, even the summer. I think you have time to make a decision. Certainly, we may know more in just one week. Try not to stress over it.
OR, and this just hit me. Start a second save, which will be a restart, then you can get that save to where a baby will be added and keep the older save just in case the EP turns out to be something that includes more for the elderly. Voilà, your bases are now covered.
