MY ds (3) has just moved into his big bed and has taken to waking up about 4 a.m. and getting into mine. I would v diligently move him out but other night was so knackered just let him stay there. ANd so it's been for about a week, To be honest my bed is easily big enough for both of us. But in the back of my mind am thinking I should get him to stay in his bed so as not to get to attached to me. Or is that just pointless?
