I think the hardest part of our TTC journey and inability (so far!) to get pregnant for me is the feeling that I'm letting people down.
I constantly feel that I'm letting Mr B down - he could be a daddy by now if it weren't for me.
But I often feel that we're letting other people down, too - our parents, our brothers, our extended family - by not having a baby yet.
A couple of weeks ago, a friend of my mum's posted this on Facebook:
I always thought that my friends posting their pregnancy and birth announcements on Facebook was difficult, but this completely broke my heart.
I want MY mum to have baby cuddles with a grandchild. I want MY mum to spoil my children. And I want to make MY mum proud.
But most of all, I want MY mum to be this excited.
I want MY mum to be a Nanny.
