How to explain to my son that he’ll be an only?

[Mooghulempress]

We’ve got a 3 year old DS and he’s recently asked a couple of times when mummy will grow another baby in her tummy. Due to medical issues, there’s zero way that can happen. Sadly I don’t think I’m strong enough to adopt, and my DH isn’t keen to do so. So he’s going to be an only. And I hate that - I’d always hoped for 2 so he’d have someone to play with. So I need a good, light way to explain to him that doesn’t touch on how bad I feel about it! Was going to go with “the lump in mama’s tummy (he knows about my tumour) means I can’t grow any more babies.” I really want to preface it with “I’m sorry”, but I don’t want to make him think being an only is a bad thing, if that makes sense?

Sorry - total ramble there but hope it makes sense!

Thanks everyone!

@Mooghulempress..firstly I'm sorry you can't have another DC. We were ttc for years and as I had DS late at 41 another never happened. You will find absolutely tonnes of great posts on this topic from those with one child and they really helped me when I was feeling depressed and guilty. I'm lucky that DS never expressed any interest in a sibling.

I have to.admit it can be hard at times as you have to be everything to your child but the relationship you have is imo really special and close and it's nice to not have that sibling rivalry and have no splitting yourself between two DC. So it has positives. As for explaining to your DS, I think you just have to say something along the lines of "mummy can't have any more babies cos her tummy says no so you are the most precious thing to happen to her".
Wishing you lots of luck and happiness..
