I hope this is not too long winded. I just need some clear advice.
I go back to work 2 weeks today.
My 5 month old son had been exclusively BF until just over 4 months, then I introduced fruit/veg purees and baby rice as he had began waking more at night.
As I've found out, weaning does not help him sleep better, despite my HV telling me otherwise.
I also didn't start expressing until 12 weeks as I was told my supply had to be established. even then, I only expressed if I was going out and DH fed him. The point is, he hasn't had much experience with bottles. Also - he won't take milk that has been frozen!
I'm nearly there..
DS wakes every 2 hours at night and I'm dreading this pattern going back to work.
I'm also worried sick that I wont be able to leave him enough milk when I'm out the house (8am til 5pm) and I've bought a bottle of formula as a standby but he won't touch it and I don't blame him it smells foul.
These worries are compounded by the fact that I feel as if my milk is drying up. DS is getting frustrated on the breast and I could not get any milk expressed off today! 
What's going on?
I have searched the threads and found wee bits of advice, but I need something specific. I know there are some very very experienced mums out there who can help 
many thanks in advance
