tie tubes?

So I always wanted 3 kids! less than 6 weeks till my 3rd baby is here. I'm having a c section. so they can just tie my tubes then. it's my husband's 1st. he wants to have one more. I do too but I get nervous because I want my kids to have everything in life. I don't want to have 4 kids and feel like a struggle or like they are missing out on anything. also I don't want to do any other birth control because I hate how it makes my body feel. what do you guys think?
