Advice Needed: Wife is losing her job soon, should I update my taxes to reflect?

I’m going to start by saying I’m definitely not an expert when it comes to taxes.

My wife is likely losing her job around October due to a company merger. We’re planning to apply for unemployment right away, but I’m trying to figure out if I should update my tax withholding because of that.

On top of that, we’re expecting our first child in November, so great timing from the universe (sarcasm).

I have a couple questions:
– Should I adjust my W-4 when she loses her job because she may not have income for a while?
– Can I claim my wife as a dependent until she finds a new job?
– If she’s receiving unemployment, does that change whether I can claim her?

I’m just trying to get ahead of things and not mess this up.

Any help or guidance is appreciated!
