Imogen ignored Teddy for the first couple of months he was here. She has very rarely hit him, although now he's big enough to fight with her, they do have some hilarious (and painful) tussles over toys. I didn't find breastfeeding a probem, Imogen would come and sit next to me if she wanted a cuddle, and I did discover at the theatre when Teddy was two weeks old, that I could breastfeed him behind her (she was insisting on sitting on my knee at the time) if I really tried. Imogen has always been a fairly independent little soul though.
