I have been with my partner for around a decade. We have one toddler and I am soon (hopefully!) to have our second child. With our first, the early months were hard going, but DC1 has slotted right in and we still have a great relationship.
However, almost everyone is telling me to expect a big deterioration in our relationship after DC2 is born, and we have friends and family who experienced exactly this, even to the point of breaking up.
Me and my partner both have siblings, and our parents have very strong relationships so I know it's not inevitable, but no-one's actually given us any good, concrete advice on how to maintain your relationship after your second is born! Help?
