LOL I just posted in another thread with almost the exact same problem!

DD did this too at around his age. It nearly drove me insane, especially since I was working part-time!

I just brought her into bed with us and bf her for a little while (I dropped that after a couple of months and started offering water). It is squishy in our bed too, we have two little dogs who DP lets up when I fall asleep. But DD sleeps very still, so we work it out. If she wasn't sleeping, then I'd tell her she must go back in her own bed. Then I decided I was sick of getting up to get her and took the sides off her cot and let her find her own way into our bed! That was even better in terms of how much I was disturbed. Some nights I'd wake up and she's in between us and neither of us noticed her getting in!

I found after a couple of months DD went back to sleeping in her own bed until about 5am, when she comes into us. So yes, it will pass.
