Hi buzybee, not quite the same thing, but when we moved from the house we'd lived in for 13 years, where our children were born and had lived all their lives, I felt just the same.Everytime I had to pass near our old house, I felt pangs and homesickness. It took a while, but now if I go back, it's just a house where we used to live, not our home.
You obviously love your childhood home and have lots of lovely memories.
Do you still have some family at your old house, if so you can visit anytime and gradually you will settle down and make the new house 'home' for you and your little girl.
Wishing you lots of luck, love and happiness in your New Home. Kacee. : )
