DS is almost 16 months and still nursing strong. A few days ago DH, DS and I were laying in bed. DS was smiling and poking at my exposed breasts (we sleep mostly naked). So I squirted him. He acted completely shocked, his jaw dropped, and he just looked at my breast. So I squirted him again. He winced away and was extremely confused. DH and I tried not to laugh, but it was really hard. So I squirted him again and he was looking really confused, then started laughing. So I squirted him a fourth time and he just laugh hystericaly. And started poking at my breast and put his mouth on to to 'mock nurse' while laughing.
It was an awesome experience in the life of nursing a toddler. When he was younger I use to spray with every let down, my milk has mostly calmed down but I never really stopped to show DS what was coming out of my boobies. I have squirted him a few times since and he just laughs and laughs.
