Travelling to Tokyo with baby

Hi, my family is planning a trip to Tokyo and staying at the hotel around Shinjuky. I am bringing my 1 year old baby along.

1) With a baby around, does anyone have any recommendations for us?

2) Which Akachan Honpo's branch is the closest and easiest access?

3) Please kindly advise where can a buy a reasonable priced Anpanman stuff like cloths, toys, and etc.
Do they available in Isetan, Takashimaya, Toys R US, or etc?

Thanks a lot in advance. Best regards,
MC

There's a Anpanman specialty shop on Gaien Hirgashi Dori near Shinjuku area, a short walk from Yotsuya-Sanchrome subway station on Marunouchi metro line.

Less than 30 min train from Tokyo is Yokohama. There is a Anpanman Children Museum, just a few min. walk from Shin Takashima station. http://yokohama-anpanman.jp

1 I think Tokyo is incovenient city for people with infant who do not have own car in Tokyo.
There are many amusement space for kids in kanagawa, but little in Tokyo.

Anyway, I recommend following shopping moll in walking distance from Tokyo Metro Toyosu station.

2 Gotanda shop is nearest.
You take free shuttle bus
from JR Gotanda station.

3 goods of anpannmann are sold at most of depatmentstore in　Tokyo,　like Takashimaya, Isetan, keio, Odakyu..etc.
Akachan-hommpo also has them.
