OMG, I feel so stupid.....
I had 2 digital thermometers.....both of the batteries were low....so I tried changing the battery on the 1 therm and I BROKE IT!!!!!!!! I opened it easily but the wire thingy broke

So now, I went and bought a battery for my Safety 1st therm (model 10430) but I got it in a bag of baby stuff at my shower and I lost it somewhere between there and my house.....

I am so afraid to change the battery b/c I broke my last one. My husband tried opening it but the top of it is really tight, and wont budge, so I am wondering if we are even trying to open it properly.

I went to the Safety 1st site and they dont have the instructions avail for download and the offices are closed b/c of the holiday. Help! Please
