This may or may not help, but my Willow is 7 months, was sleeping through the night starting at 6 weeks and then poof, started waking up between 2 and 3 am every night.
We switched diaper brands. Turns out she was waking up because the ones we were using just weren't giving her that dry feeling. I don't advocate one brand over another, I think it's just individual babies' preferences, but maybe give that a try?
And OMG do I hear ya on the cost of formula!!! Hubs and I call it "powdered gold", I breastfed for the first 3 months and then just stopped producing milk, it hit me emotionally but WOW did the wallet ever take a beating! Our doc told us that we can switch to milk at 9 months, I'm looking forward to that :)
