When my littlest DD was born she brought some presents for DS5 and DDalmost8. They each had a T-shirt which said Big Brother/Sister - they loved them and they insisted DH wash them each night so that they could be worn to the hospital each day. I think it also allowed random strangers to make a big fuss of the 'big' kids because it advertised the fact that they had a new baby. DD7 also received a Beados kit, which was great because it entertained her in the hospital.

We also didn't allow anyone to see the baby until after the big kids had and refused to reveal the gender until they had met OUR baby. Always 'our' baby, never 'my' baby or 'mummy's' baby. My kids are fantastic siblings and number three has fitted in very smoothly with no jealousy issues. Be sure to pay your DD plenty of attention and let her be involved in making some decisions for the baby such as what to wear.

Good luck and enjoy!
