Hello there! If nobody has the time or mood to, then there isn't a reason that you should be trying to get it done :)
Life after having kids is a lot more than just one more member in the family - juggling between work, family and personal time is really tiring and exhausting, and more often than not, most people have little/no balance at all.
Sometimes, it could just be us being too busy, or it might also be having the thoughts of "what if"s after doing the deed - so it's okay not to! I can honestly tell you that most people don't have the time to, even if they do want it :x
