My 18mo DS has been a very challenging baby. I know these things are relative but that's been my experience of him. He was a 'reflux baby', hugely emotional, demanding, impatient, many tantrums from very early on and unable to take anything 'in his stride', every tiny thing is the end of the world 
. We love him to bits but when people ask us if we will have any more we have been known to laugh hysterically before yelling "are you f*cking joking??!!" and then crying .
In fairness, I had always thought I might be happy with one. DH had said in the past he wanted at least two but now he is adamant that we're 'one and done'. Soon after he was born I had the coil fitted and we began giving away things he had grown out of and would no longer need which shocked some of our friends but I guess we were very certain even that early on that we wouldn't have any more.
I know he's still very young but his language is beginning to pick up and I want to be prepared. AIBU to tell him a white lie if he asks for brothers and/or sisters or why he doesn't have them? I was thinking along the lines of '"you're everything mummy and daddy need and we want to focus on you"? Which is actually true too, it's just missing out the bit that says how much he's drained us! Apologies if I sound very negative, I've had PND which is beginning slowly to get better. Despite this, I am hugely grateful for him and he is my world! I welcome any suggestions of how to deal with questions about siblings in the future. Thanks for reading x
