Throughout my whole pregnancy with Gwen I made every effort to include Symphony. She helped pick the nursery furniture (and even helped build it!) and went baby clothes shopping with me all the time. She was present in the delivery room when her baby sister was born and even picked her middle name (sort of; she suggested Viola which became Violet). Of course, she was 11 at the time, so it was a little different from going through this pregnancy with a 3-year-old.
From the very beginning I talked to Gwen a lot about the baby in mommy’s tummy, how soon it would come out and live at our house and be her friend. When we switched the girls’ bedrooms we let her pick which side would be for her and which would be for the baby, we bought her a toy baby of her very own and got a book about a little girl who gets a new baby sibling to read to her (which I still can’t get all the way through with out crying…). Of course I was still worried about how the changes would affect her since she is still just a little kid.
Thankfully so far both girls seem pretty enamored with their new baby brother. Gwen always wants to hug/kiss/pat him and says “awwwww, that baby so cuuuuuute” (or more rarely “Nicky so cute” because she has an aversion to saying names and tends to call most people “that boy” or “that mom” or “that baby”). She helps by bringing him his blankets and his lovey and talks about how when he’s a little bigger she will share her toys with him and they can take a bath and go to the park and do all sorts of things together. For Sym of course this new baby sibling business is old hat, but she still likes to watch him make his tiny funny faces and wave his tiny hands around. She’ll help by giving him a bottle but she draws the line at diapers (I don’t blame her; Nicky is kind of a poop machine rn).
