DS2 (23 mo) is a grumpy sensitive child and his own bedroom was always 'his' space iyswim.
Whilst DS1 has been desperate for DS2 to move in with him forever (DS1 has always known that was the plan when we did the bedroom up for him with bunk beds) I really think that DS2 is going to hate it as DS1 is a bit 'in your face' and annoys DS2 a lot of the time (whilst at the same time they dote on each other and DS1 is the only one that can make DS2 giggle
)
We need the space but I am feeling so sorry for DS2
