Hello Manish. Welcome to the forum.
So, you've been seduced by the undoubtedly fascinating Bengals, eh? I think Dawn has summed them up, and given you the benefit of her experience straight from the horse's mouth. They have a reputation for being quite high-energy, demanding cats, and it's quite an undertaking to adopt one, even when you have no small children.
I'd be a little wary of having such a young child and a young kitten in the house together, but that's because I don't think it's ever a very good mix unless you're fully prepared to be ultra vigilant, and I don't just mean in terms of hygiene. As a first time pet owner you may not be prepared for all the wily wheezes cats have, regardless of breed. Put them together with the wily wheezes and grabbing instincts of babies and toddlers, and it can be an interesting (and potentially explosive) interaction.
That said, there are plenty of people who are living testimony to cats, dogs, kids and other pets all rubbing along perfectly well together. Much depends on how committed you are to making it work, and to keep going when things get tougher than you initially anticipated. And that's not a personal criticism of you - I'm just thinking from my own experience.
Back in November last year, as experienced and long term cat and dog owners, we adopted two small semi feral kittens. They've tested us to the limits in the 7 months we've had them, and driven us to distraction at times. There was one occasion when we had their things packed and had rung the shelter admitting defeat and requesting that they allowed us to return them. But we didn't. We kept going. They're still trying us to distraction - and Dawn will probably say the same thing about her cat family too
If it all got much tougher than you anticipate it might, would you have a sound back-up plan? There are so many cats who end up being advertised "free to good home" or on Gumtree and Freecycle because people have bitten off more than they can chew. It isn't fair on them when they become "surplus to requirements."
It's great that you're posing the question, and really thinking about it before you've actually brought the cat home, but think of all the things that could go wrong, double it for a normal cat and treble it for a Bengal.
