I found a great self published children's book for DD called 'Learning to Wean'. It helped her through the process of understanding a new baby was coming/here and that she could still always enjoy mummy cuddles. She loves that book so much and can recite it. It was so effective that recently when she was quite ill I offered her boob feed and she rejected it for a boob cuddle instead, saying boob milk was for babies. I was surprised as I thought she may still want it as she saw her baby brother feasting regularly.
