Tanya - Zander wakes anywhere from 5 - 6pm last nap of the day, and his last nap is just that - usually only around 40 mins.
kuraiza - why beating yourself up? Do you feel guilty or as though you havent done the best you could? You have done the best you possibly could, there was a reason you introduced formula - you had tried other options which didn't work - try not to second guess yourself or feel too bad - Jude will be grateful for having a full tummy I am sure. I know you might think easy for me to say - I am still b/f - but i have had hard times with all 3 of mine - and we do the best we can at the time.
I wouldnt agree with any sleep school that says to control cry under 6 months either. Babies need to know you will respond to them - when they hit that magical marker they come into a new awareness and test us a bit more, so in my opinion, a bit of crying then is ok if it is ok with your family.
PP are you saying you might be UTD????!!!!!! Nauseous - freaking out .... will stalk you on FB now LOL :ROFL:
