Thanks everyone for your replies.

We have had another talk tonight and discussed the pros and cons. DH said that he doesn't want me to agree if I wasn't ready. I actually really wanted to get pg 2 days after having Amy as I had a fantastic pg. So I will go and get checked out, get my bloods done and talk with my Ob. If medically I am okay we will start TTC next month. Emotionally and financially we are good.

DH has done the night feeds since Amy was born and I have slept though almost every night. I may be going back to work next month and DH will be a SAHD and it will be the same with the next one. He really looks after Amy 50% of the time so it has been a breeze for me. I didn't have much milk (because of a breast reduction) and Amy has been on formula so my body hasn't been under stress from bf. I just started taking folate again tonight.
