What exactly do you do all day?

I am 6 months pregnant with number 2 and I find it hard to want to take my son play outside when it’s rainy and cold and he gets cabin fever really quick. I’ve taken him to indoor play gyms but there’s so many older kids that go (3-5) range and I’m afraid they will trample him when playing. My son is very small for his age. Also I have to climb in the tunnels with him and that’s just beginning to be difficult for me to keep up with. I don’t mind going once a week.

But we mainly do the same thing over and over and I’m afraid he would be better off going to a class or daycare. I feel like a terrible mom.

We will wake up, eat, and watch cartoons. Play with legos, toys and indoor slide that we have. Then lunch time and after lunch he watches 30 mins of blippi and may get a nap but sometimes he totally skips and I understand that’s probably because he isn’t getting stimulated enough. Then from 1-4 we usually play with toys until dad gets home and then he gets super excited and dad will throw him around and horseplay which he loves. Then dinner, bath, reading, more playing and bed. He’s goes to bed without an issue and sleeps all night. I just feel like I could be doing so much more with him.

Any suggestion would be appreciated.
