It could also be the cognitive therapy stuff my gorgeous psychologist taught me about recognising my negative thinking patterns and changing my thoughts to more positive ,realistic ones. For example, instead of thinking "Oh god...I am SO tired. How am I going to get throught the next few hours". I manage to think "Yep...I'm pretty tired but I'm tired and happy and nothing is actually WRONG". This is not rocket science I know and the rest of you probably do it without thinking about it or having to pay someone lots of money to remind you but that's the way my brain is.
Whatever the reason...fewer breastfeeding hormones......the end of postnatal depression.....more sleep.....smarter thinking patterns....life sure seems more sunshiny and my husband seems sweeter. I even think I love the dog!
