Advice on Rehoming 7-Month Kitten

I’ve had my kitten since he was 4 weeks old, he was find by my boss at the vets office, obviously on his own and covered in ticks. I admit it was an impulsive decision to adopt him as I was freshly pregnant at the time and my husband was never happy (and still isn’t) with my decision. He’s a sweet, albeit somewhat standoffish kitten, full of energy and a desire to be near us most of the time.

The issue is that my chihuahua (6 and a half y/o) does not care for him due his constant attempts of ambush play. It’s become a constant negative feedback loop where now the kitten is obviously scared of both dogs in the home (my other, larger dog is chill and used to baby him), getting more aggressive with them even with my attempts to intervene. It’s gotten even worse with my baby being born about a week and half ago, even with my best efforts to prepare him, the babies cries terrify him.

I guess what I’m asking for is advice on how to rehome him, like red flags to look out for, how to make the process less stressful for the kitten, etc.
