Try not to worry too much about "losing" your identity. While you may shed layers of your former self, you are creating a new existence. Adapting to your new life can be lonely in the early months, but know that nothing is forever. Your old self might rest dormant for a while, but it will burst into new life, as you become a more evolved version of yourself.
My best mate is turning 30 in November, and has sadly told me, instead of having a full on two day bender of a birthday, she is keeping it "low key", because sadly, she doesn't think any our friends would come. One of the babies is teething, the other isn't sleeping well, one can't afford the trip... etc.
Are you amongst the small number of parents who are thinking about what is still an unusual and some might say repugnant practice of helping reduce the risk of post-natal depression and increase your 'happy' hormones? ...

To coin a phrase from a former Princess, there are three people in my marriage. Me, my lovely wife, and a fictional schoolboy wizard with a lightning bolt scar on his head. A Mr Harry James Potter. I even know his middle name. He is a constant presence in my home, a menacing bespectacled spectre in my day to day life.
Off my face on painkillers and hormones after an emergency c. section and haemorrhage, I was repeatedly pressured by a sales rep to buy baby photographs. She kept returning to see if I'd 'made a decision'; I could barely decide which way up my baby was supposed to be. Of course this should be banned. It's borderline barbarism and places commercial factors above maternal wellbeing.
