Assuming you celebrate Christmas you might try out a polar express type train activity next December. I think Essex has one that is supposed to be the best in the state. We went to one in Thomaston this year. The three year old loved being on a real train and meeting Santa (first year he has) and the 11 month old literally was in disbelief when she saw Rudolph. They both carried around the bell they were given for days.

We did the lights at lighthouse point earlier in the month. It was the first week and right at sundown. It was deserted and we were able to drive through a few times. The fantasy of lights or whatever it’s called up at UCONN is a nightmare. The kids loved it, but nothing like paying thirty dollars to sit in bumper to bumper traffic for 90mins. An hour in line for a half hour of lights. The lights at Hubbard park in meridian were decent, and free. I think arriving before dinner at like 5pm is the best idea. The least amount of other cars.

Otherwise you seem to have a good plan for the week. Kids also seem to love being outside even in cold weather. Parks are always a good way to tire them out and hope for a proper nap.

On Friday and Sundays Extreme Air in Cheshire has the morning reserved for toddlers (really like 1-5 year olds.) also a lot of fun. It is a trampoline park. Last time I took my son he had the time of his life, but crashed with like 15 mins left. Could barely walk. Napped well that day.
