Am I in the wrong

If the older ones won't share then your youngest doesn't have to either I don't believe in making kids share anyway, we would hate it as adults if we were expected to let others use our car/phone/favourite belonging without any say at all

@Heather thank you I agree it’s not fair

I'd say you should treat them all the same. If they don't share, they don't get shared with. There is no good reason why the little one should have to but them not.

Maybe have some "family toys" available like jigsaws, colouring stuff so they can learn to share those but personal toys no. Your partner isn't being fair as HE isn't treating them the same. If he wants a 17m old to share then he has to do the same for the older 2

Why is your partner not parenting his other 2 kids? He should be teaching them about sharing in general and not being dicks to their younger sibling. At 3 and 6 both are old enough to know better. You really oughta mention it sooner rather than later otherwise YOU will be the one suffering the consequences of bad behaviour with your own child when the other 2 go back home.

@Neena I think it’s because he sees them 1 a week he allows them to do what they want unfortunately so they don’t get upset and want to go home as that happens with the eldest tell him no and he cry’s to go back to mummy as we are being horrible in his words

Incog - yea that shit never ends well. He’s their parent, not their friend. At those ages, kids know how to push boundaries to see what they can get away with. My friend is living this current nightmare. Her partner had a 5yo boy when they met. He only had him once a week too. He was an absolute terror and would swear at his dad and tantrum/scream when out in public if he didn’t get his way. She now has a baby and his kid is now 6 and as predicted, his behaviour has escalated. He is jealous of the baby and has tried to hit baby. He will tantrum if her partner is holding baby until he gives baby back to my friend and his dad will go buy him a toy or go McDonald’s. The dad can’t be arsed to discipline him - would rather do/buy him what he wants for ‘an easy life’. But he doesn’t realise this short sighted gain is only going to get worse in the future. My friend is now planning to split with him as she can’t take his kid’s bad behaviour anymore, worries how it will impact her own child.

@Neena I can’t understand how that must be difficult for your friend I hope they manage to sort everything out it’s never nice luckily for me I’ve never had the issue of hitting but I toatly agree with the things you said like an easier life going to take everyone’s advice on board and speak to my partner try come to some agreement that helps both sides

Tbh kids at the age of 17m don’t understand the concept of sharing so he’s prob not learnt it from them. He just acting like any other toddler of his age.

@Lauren it’s hard to say that when he shares with my 4 year old sister and he shares with his friend the same age only has an issue with them two don’t get me wrong he don’t share everything but he understands the consept
