Good on you for breastfeeding this far! What an amazing effort and when I think about it, no wonder sometimes breastfeeding can be difficult - look at what a great bonding experience and how beneficial it is for your LO. Are you taking any multivitamins or iron tablets or anything to help with your energy levels? Also.....just a thought, do you think because in your head you are/were so set on BF until your DD is 2 and now you are feeling run down that feels like SO far away and it's just taking it's toll? Whatever you decide, congratulations on making it this far and make sure you make the best decision for you both.
