I have a 13 month old that only has three teeth (one just popped through two days ago) that gags on anything less then puree foods and loves her milk (breast milk). When should I stop pumping and switch over to lactose intolerant milk? I know she is lactose intolerant because the whole time I was pregnant with I was. I also have another kid that is the same way. Now days the 1/2 gallon of silk milk is about 3.77 per 1/2 gallon (super expensive ). That being said I just don't know when the right time to stop pumping is (also without being judged that she is older than 12 months)...any advice? TIA
