We have had the Michael's Big Bed set up in the boys room for a couple of months now, and have only been able to get Michael into it while asleep. Its pretty crowded in there with Marcus' bed and the cot too. We have promised the cot to Sharon and Andrew next door, and time is ticking away - she's about 4 weeks from delivering.
Elf had the inspiration to paper the walls with Wiggles paraphenalia. We did it this afternoon, and this evening we could hardly hold him back. Michael hopped onto the bed, lay back with hands behind head, and said "put a blanket on me, Mummy". He is sleeping there beautifully as I type.
