Hi Karen,
I moved appartment almost a year ago now when my DD was more or less your DD's age. We were lucky to be moving to a place near my MIL's so she basically 'had' her for 5 nights so that we could get the place sorted (we were still having bathroom and decorating done so it wouldn't have been a good place for her to be - plus we didn't have a kitchen for 3 weeks after moving in
but luckily MIL's cooking is delicious
)
Anyway, when we finally decided the house was a decent place for a bubba to be, I put one of her favourite teddies/toys in each room and as we went through the house I made a big deal about how "so and so" was sitting on the sofa or " so and so" was playing in the kitchen etc, etc. My DD had never had her own room before as we didn't have a room for her in the other appartment so we really laid it on thick how lucky she was to have her own room and how big it was and how all her 'friends' (toys/teddies/dolls) loved it in there. The transition was smooth and she slept all night in her new room.
Good luck with your move.
Just curious, where are you moving from/to?
