Sweetie it's not going to be too bad, honestly!!!! You will be just fine, although I do hope that your LO crawls first because it's a nice way of introducing you to what they tend to get into
and it's amazing how high LOs can reach when they start walking.
I don't believe in completely baby proofing houses, BUT you do need to have a very good look around and find what is dangerous. The powerpoints should be plugged, excess wires stored together as much as possible and out of the way as best you can. Little bits and pieces picked up. So electrical hazards, choking hazards and falling hazards are probably the best ones to start with. Make a list now and begin cleaning up now...it makes it that much easier.
You do start walking into new scernarios with a fresh pair of eyes once your LO gets moving. I find the exosaucer very handy for when I need my LO up off the floor...I don't leave her in it for long, but I know she is contained and reasonably safe there, but for the most part you are with them so you can distract and remove them from more dangerous areas.
With your tv could you put some boxes or a table infront of it so your LO can't try and pull up on it?
Mainly just wanted to send some hugs and let you know that making gradual changes will help to ease your anxiety, you don't have to be super neat, but aware and on the ball
