Have you been in the situation?

Try to incorporate her with taking care of the new arrival . . . It can be a great bonding experience for everyone and letting her help with picking out clothes or getting supplies for you can make her feel important. . . .and then you can make sure to praise her for being a great big sis also make sure to still plan quality time with her . . . . It may take her a bit to settle in, but she'll get there as long as she knows shes special and loved. And Congrats!

Yes, I have been in this situation all the times, as an aunt to 3 and a mum to 2.

I was pregnant with my second child and my daughter Kayla was looking forward, pretending that her Baby Annabelle was it, I couldn't wait for her to interact with the newborn, I gave birth and my husband took her to see her, she was excited but then when she came here, she suddenly changed as she saw her cuddling it, Your daughter is insensitive about your newborn, You should give them both the same attention, maybe a little bit more to the 6 year old.

Nope, I have one child, never been in the situation, But pay attention to her, when everyone was taking pics, you should've been distracting her from it all. Pick her up, tickle her, kiss her, hug her. Then show her the baby, let her hold it, kiss it, talk to it. Pay attention to both your babies.

Make sure she knows you will both be the same around her. Make sure there's often at least one parent with her
