Mamma, Congratulations for not leting your baby cry it out! So much better for your sanity, and the absolute best for your baby's mental and physical health.
All babies are different, and what works for one may not work for any others.
He may have a problem with the formula.
Once awake in the early AM, that may be HIS time. You would do better to move to a different time zone, in his book.
My baby didn't sleep through the night in anyone else's book for 2.5 years. That being said, we coslept with our second from night one, and he slept SO much better!
I think I posted most of the contraindications for bedsharing in another post, so look my answers up (today's in fact, I think!) but contact La Leche League for a really comprehensive list.
All babies are different. What works for some will be viewed as torture by others, and vice versa.
Let go of your frustration, get sleep at different times, and enjoy your baby. he will be this size only once. That is the best and only true advice I can really give.
And congratulations on nursing your baby for a full 6 months! So many doctors are not current in their reading that the AMA advocates a full year - the WHO advocates weaning some time after TWO full years. (Why is that? Big pharma wants to sell you formula that's why? why? nothing to do with third world countries' water supplies - SWEDEN is not a third world country!)
pat onthe back to you for not letting your baby cry. I love to read that every time,
Good luck,
M.
