I think once your children reach a certain age that you should stop breast feeding. I wouldn't have my 6 year old son latched to my tit. The boy in the video looks to be a bit too old to be latched to moms teet but I've heard of some women breast feeding until the childs age of 2 years (which is the age most kids are recommended to drink whole milk). Also, when they start to get their teeth in, that is a sign that they are ready to start more solid foods. Not saying they won't need the nutrients from breast milk because that does provide most of the child's nourishment. In my opinion, the age of 2 should be the limit but there are some extreme cases where women breast feed older toddlers (which is mad fucking crazy). Those babies can eat a t bone steak and you got them sucking at the teet. Hell no!
Kind of off the topic but....
Camel's Milk is said to most closely resemble Mother's Milk & has been used to treat autism.
Some Mothers with autistic kids have claimed that they've shown remarkable improvement after ingesting it.
It's hard to come by tho. While the US allows liquid camel milk to be sold, It has to be pasteurized.
Canada does not permit the import of it in liquid form. Only in powder.
It's very expensive tho.
