I suggest that if you can show her your new house before you move you should. She might take it a little easier if she gets to see it and when you show it to her, use your imagination and make it a fun trip. Tell her where all her things will be and let her help imagine it too. If your going to redecorate the house take her on a special trip to a craft store or something to pick out stickers and border paper for her room. My daughters only 2 and she already loves decorating her room. I think if you can show her how fun and excited your new house will be it will be a lot easier for her and also explain to her that she will get to see her grandparents still even though you guys are moving. Maybe when you guys move throw a small family dinner party and then she can see for her self that the grandparents can still come over. Good luck and hope you have an easy move!!
