I've found that children who attend one day a week generally need up to 6 weeks to settle in. Children who come three days a week need up to 2 weeks to settle. The difference is not the number of days, it's that they need 5 or 6 goes to realise that it's OK. I estimate that about 1 in 20 children need longer than this.
I know you can't change things now that you did, but her first day in care, especially if you're at home, should have been really short (like 3 hours, or even 2 if you knew she'd been crying, and I'd have called you if she cried for more than 1 hour) It's something to think about next time you give it a go - the more gradual entry is always a winner. Yeah, you're not getting "value for money" (At $70 per day that works out at $30/hr!) but in the long run, it is more worthwhile.
It is absolutely OK to cry; I know loads of mums who have done it, although very few do it where we can see! When I do see it though, it reminds me of how important my job is and makes me want to pour a little more love into all the children!
As for your other options, you could get an awesome cleaner for less than a day at childcare, so I say go for it! You can convince your DH!
Alternatively, get some "home help" in after you have number 2, see if they can clean while you leave the baby at home, and you go out and have some special time with your DD. That way, your house gets cleaned, and you get a bit of time off. There are loads of nannies out there who do afterschool work that would love a few hours before 2:30.
I hope it all works out for you!
