Josh is sleeping through the nite now only sometimes waking up for a feed he goes down at 8 and wakes at 7 the next morning. If you feel formula is the way to go ... your the mother you know best, do it. I use NAN HA1 and Josh is so settled with it, i have also started him on a teaspoon of Farex a day mixed with a teaspoon of fruit and his milk i feed it to him using the spoon, and he is great! Maybe your little one may be hungry? also try wrapping him tight, this always works. I may be wrong, but this works for me, hope it does for you! He may be teething early also?
