That's it really. We've got two little ones together too and are married, but I wondered if it was better to wait before pooling savings (as deposit) / mortgage until his other kids (DSKs) are 18. I don't want to disinherit them (it's a good relationship!) but don't want crazy exW to try and get her hands on anything to do with my DC either.
Unsure of the ins and outs.
