Same here dd was one week shy of 3 when her brother was born, she nursed alongside her brother, at first it was hard - I'll not deny it, she wanted to nurse just as much as her brother, and then she realised that she was spending far too much time nursing and not enough playing that then she managed to regulate things so that she only nursed when she really needed it between 3 and 5 times a day in the end. It did take alot of patience to 'wait it out' but it worked in the end and then they would invite each other to nurse, it was quite cute actually, she continued to nurse alongside her brother for 18 months and CLWd it really was on the whole an excellent experience for us all, albeit there were moments when things were harder, Adventures in Tandem Nursing by Hilary Flowers is a very good and honest book about all the aspects of Tandem Nursing.
