First time I was planning to wait until about two months to tell our parents. I ended up telling them a little earlier cause I couldn’t keep the secret any more (I am like that with my personal secrets, I have to tell someone sooner or later!) I told my siblings and a few close friends by the third month.
Second time, I told our parents a little earlier than that since opportunities arose to break the news. I’m hopeless at saying something like this so blase that I have to hint it very strongly, and a good opportunity came up in the conversation. With my eldest, we had just come back from holiday (we found out the day before we left that I was pregnant) and speaking to my parents, they said that when we have kids we shouldn’t just expect to leave the kids with them for two weeks whilst we go jetsetting. I said well it was a bit difficult to do that this time. My parents asked me what I meant and I said well it’s hard to do that when the kid is attached to you!
