I had a sort of similar situation. So J sees me nursing Leo all the time. NBD
The other night I got my pump out and was pumping upstairs where I was suppose to have privacy. All the sudden "MOM, MOOOOM, where are you." Mind you I just told him I was going upstairs. Then he comes flying upstairs to see the pump attached. Sigh, that was a very long conversation plus sitting there with your boobs being squeezed by a pump is a very vulnerable place to be. I just wanted him to leave and go back to his cartoon lol.
Eddy, I have been wondering about this. Are you nursing in front of your oldest, just not pumping? I'm going to be alone during the day with DS and kid # 2 and I just assumed I would pump and nurse in front of DS. Except he is 4, and asks alot of questions. I suppose I just tell him that boobs make milk and go about my business?
I thought it would be a bigger issue but he doesn't even care. The first time I did it I just told him my boobs made milk and this is how I feed Leo. I nurse in front of him all the time and he rarely even gives me a glance. I had not pumped yet so that was a whole other battle of questions. Pumping was much more of a curious thing to him then nursing.
Lol. DS barged in on me when I was going to the bathroom about a week after DD2 was born, so the squirt bottle was in use. He took one look, saw blood and ran out to the living room telling my dad that "Mama's bagina (working on pronunciation) has an owie. A big, big owie." Needless to say, my dad was laughing at him.
He also watches me pump every morning, and sometimes will sit beside me watching saying, "Fill it up, Mama, fill it up". Apparently, he thinks that he is going to be a coach or something...
