just wanted to say scheh that you know your baby better than anyone, and you do whats best for your baby and your family as a whole. for our part we resisted doing cc for a long time, and tried everything else. we co-slept for a while (really didnt want to as i really need space in bed due to back and joint problems), and it did work for a bit then we got to the point where we were all just waking each other up all night, even when we put him back in his cot. with the constant night waking and screaming (despite being cuddled/rocked/walked around) we decided to try cc as a last resort. it worked very quickly and N has been a much happier baby as he sleeps so much better now. he can settle if he wakes himself up, and only needs 2 feeds through the night (as opposed to the hours spent on my boobs comfort feeding)
i'm also a better mother. i'm no longer crying all the time because i'm knackered. i have the energy to interact and play with him that i've been lacking for some time, and me and DP get on so much better because we're not so tired.
i know its not for everyone, you have to find what works for you, but you should never feel guilty for it - agree theres so much guilt as a parent already, so dont heap more on to yourself!! i also agree with mama, as long as your child is loved then in general the choices you make as a parent are right for you at that moment in time.
finally fwiw, N is similar in that he does like to be carried about, and he's not a baby you can just sit on your knee either! i did get a sling which was ok for a while, but my back probs are getting worse so cant really use it at the mo. hope things are improving for you, at least theres a great bunch of people on this thread (and MN in general) for support
