We planning and hoping on B #3 so when we do have the baby my DS1 and DS2 will need to share a room as we will be living in a 3 bedroom house. The house we will be living in the rooms arnt the biggest. So what do you think is best to use

1:Have to seperate single beds for them
2:Bunk beds (not so sure)
3. 1 single bed that has a trundle so they both have somewhere to sleep when comes to bed time but the the trundle can get pushed back under when its not sleep time and they have room to play etc.

what best worked for you when your children shared rooms would like to see what people think and if you have any more ideas please share thanks.
