my younger two are 19 months apart. We conceived #3 when #2 was 10 months old. I was fully b/f too.

My DH is a firefighter - therefore does shiftwork. He is home 6 days out of every 8 - although he isnt in the house, he is in the garage, but if i need him, i can call upon him.
I do my housework in the night, when they asleep. My days are too hectic to be worrying about cleaning the stove, or mopping the floors. I pick up things here and there, and will hang washing out. But day time is the girls time with their mummy.

I found the first trimerster of pg hard with two little ones. ALl i wanted to do was sleep, yet i had to care for them.
Some days are harder than others. Some days i think to myself 'what are you doing?'.....i think if your pondering the idea your decision is almost made for you. Its hard work, but its a fun hard work, if that makes sense...

goodluck!
