When travelling with kids to Bangkok, you can't start exploring the sites immediately. Avoid iconic attractions such as; the Grand Palace on your first day, the crowded precincts of this very popular site, may not be conducive to kids, just after a long flight. Forcing them to hit the sites on day one is a recipe for a major tantrum, right there at one of Thailand's most prominent temples. You could opt to stay in your Bangkok, hotel, hit the pool, relax over a meal and plan a leisurely scout of the neighbourhood once the outside is cooler and kids are more rested.
