to YT... Keep in mind your baby is only 4 mo's...so she's got a ways to go with the training
At 4 mo's you should be watching her very closely and I wouldnt recommend leaving her unattented on a couch, bed or anything else for that matter... until she's trained better...
Also, I always have Meka sit a good distance from me when cleaning any accidents... they can smell so well (10x human), that I always think any chemical might be hazardous to her... but thats just me... Hope this helps, and cant wait to see pics
