Probably not and the older he gets the more it will develop. I still have to feed Tink sometimes in public, she gets tired quickly because of her asthma and won't wait for food if she's tired, she just climbs on my lap and turns into position. She's 26 months now and I really do get some comments.
I got told off at the breastfeeding group because I said one thing about her being so small is people weren't going to notice that I was feeding a 1 year old in public. I can see the point and now don't care if she needs it she needs it. I just get annoyed that I can't get up and say something to people because I'm feeding her.
Reading of others nurslings shouting "boob" across the room makes me so glad for "me me"!
I found a great chart for showing the benefits of nursing long term.
If you breastfeed for a few days, your baby will have received your colostrum or early milk. Packed with optimal nutrition and antibodies, it helps get your baby's digestive system going and give him his first - and easiest - immunization.
If you breastfeed for four to six weeks, you will have eased him through the most critical part of his infancy. Breastfed newborns are much less likely to get sick or be hospitalized and have fewer digestive problems than artificially fed babies.
If you breastfeed for three or four months her digestive system will have matured a great deal and she will be much better able to tolerate the foreign substances in artificial baby milk.
If you breastfeed for six months, she will be much less likely to suffer an allergic reaction to artificial baby milk or other foods. A new study indicates that nursing for more than six months may greatly reduce the risk of childhood cancers as well.
If you breastfeed your baby for nine months, you will have seen him through the fastest and most important development of his life on the most valuable of all foods - your milk.
If you breastfeed your baby for a year you can avoid the expense of artificial baby milk. Many health benefits during this year of nursing will last her whole life. She will have a stronger immune system, less chance of childhood and adolescent obesity and will be much less likely to need orthodontia or speech therapy.
If you breastfeed your baby for eighteen months, you will have continued to provide the highest quality nutrition and superb protection against illness at a time when illness is common in other babies. The US Surgeon General says "It is the lucky baby that nurses to age two".
If you breastfeed your baby until he is ready to wean, you can feel confident you have met your baby's physical an emotional needs in the most natural, healthiest way possible. In cultures where there is no pressure to wean, children tend to nurse for at least two years. Mothers who have nursed for two or more years have a lower risk of developing breast cancer.
Don't worry that your child will nurse forever. All children wean eventually no matter what you do and there are more nursing toddlers around than you might guess.
