Narita airport is very far from Tokyo city centre. The major hotels in Tokyo all have "limousine bus" (not at all fancy) service to Narita for a charge.

Those who are more familiar with Japan are happy enough to take the train (quicker), but I wouldn't recommend it as a first timer - the massive train stations can be intimidating. And with all that luggage you'll want to take the bus.

You have to carry your luggage on board the shinkansen. However, you should look into the "black cat luggage service". For a very reasonable price they will move your luggage from hotel to hotel for you.

These are good recommendations.

Take a limousine bus from Narita straight to your hotel (assuming you are staying at a major hotel on the route).

Note: The "black cat" service is called "kuro neko" in Japanese. This is the company symbol. They can transport your big luggage from your Tokyo hotel to elsewhere, for example to the hotel in the next city you'll be visiting.

I also recommend the limousine bus if you have three large pieces of luggage. On the following page choose Narita Airport routes and pick an area of Tokyo to find a list of hotels.

For example choose Shinjuku > Hyatt Regency Tokyo to display the timetable.

Alternative: ship the luggage from Hotel to NRT with a service like https://airporter.co.jp/ and take the train.
Given the typical checkout at 11 and flight at 17 this leaves some hours hands free .

Some important clarifications to really provide good advice...

Where are you coming from prior to departing from NRT? Presumably somewhere besides Tokyo, based on your phrasing? If so, how are you traveling to Tokyo - specifically trying to narrow down your arrival point into the city. The reason for asking is that recommending a hotel in area X may end up being inconvenient if you're arriving into area Y from elsewhere in the country.

What is your budget range for the hotel for that night?

Will you have a JR rail pass valid on that last day that you're planning to use for final rail transport to the airport?

Limo bus is an option but depending on your starting point, the two dedicated airport express train services are faster and not subject to traffic delays (and for the N'EX, no extra cost if you have a rail pass valid that day). Tokyo train stations are extremely user-friendly to navigate even as a first-timer, with clear bi-lingual signage. The airport express trains have luggage storage at the entrances to the cars for suitcases and overhead shelves for carryons. Note the Shinkansen (bullet) trains don't service NRT.

Don't know about your travel during the trip but if you're already set up for taking the bags and the kid on trains around Japan before you get to NRT to return home, then you likely aren't concerned about one more quick train trip to the airport. You'll see other families with young ones doing just that. But if you're traveling through some other means and/or don't want to juggle all of that in getting to NRT, you may prefer the limo bus. In any case, whichever option you end up using, more details would help with more relevant hotel recommendations.
