congrats on still breastfeeding! :D i hope you know you are giving your child the best start!
crying it out is hard on a child, so im glad you have chosen not to take that route.
however, somehow you need to get sleep and you want to be a wife again.
no one really tells you once you have children you never sleep again. :P its true. so do what you can to get you all the most sleep.
cosleeping is safe and effective and gives your children a sense of security that cannot be replaced. parenting is night and day for the rest of your life, and though it may mean sacrificing "normal" sleep, the more responsive and loving you are to your children's needs, the happer and more confident they will sleep as they grow! :D
anyway, most importantly trust yourself on this. you do need to be a wife first, but you do need to support your kids's needs too. its a tough balance. just follow your heart and know taht what each of your kids are doing is normal, its not out of any bad choices you made as a parent, they just both need your love and attention. do what you can, and what you feel is best for your family! :D
