surprise baby #3

just took a test because my period is late and it always is because I am breastfeeding but I figured why not. didn't think it would be positive but it is. my second daughter turned 1 yesterday. I am a stay at home mom because my salary only covered my daughters daycare and nothing more. my husband doesn't make a lot of money and I am actually terrified to tell him I'm pregnant. I don't feel like he will be excited. anyone have any thoughts or advice.
