A lot of you have posted dairy products -- butter, whole milk yogurt and the OP said non-dairy right? Having a child who could not have diary products (including casin, whey, yogurt, butter anything derived from milk), it is extremely hard to get the "fat" this mother is wanting or doctor is suggesting there is a need for.
I would suggest to the mother to continue to breastfeed an ensure that the dc is getting plenty of the rich hind milk. One great way to do this is to always starting nursing on the side last nursed or at least 2 nursing per breast before switching. Increase nursing rather than increasing foods. Foods for infants (even at 1yr old) are more for learning than sustainance. The bodies ability to digest and utilize the nutritional value from food is not fully developed.
As for making up for it in foods -- if the family is not vegan or allergic egg yolks are good. Coconut milk full fat is also a great suggestion. My son loves bacon
: high in wonderfully not health animal fat and nitrates. Alvocados was a good suggestion as well. It is extremely difficult to equal the fat of cows whole milk in non-dairy foods. Goats milk would probably be a good source of nutrition and fat when the non-dairy is refering to cows milk due to allergies and not diet preferences.
Baby's need fat for brain development till at least age 2. That is why peds say whole milk to age 2, then low fat.
Honestly, I worried over the fat issue, but he is so limited in what he can it and what he would eat that I was happy just to have him eating something that didn't make him sick. I nursed him until he quit on his own just days after implantation of my surprise dd. I ate a restricted diet myself while nursing for a year and a half to keep him from having intestional upset from a variety of foods.
I did talk with our family doctor about his not drinking milk due to allergies and he was not really concerned. My ds2 is short and a light weight he's almost 3 and weighs between 23 and 25 pounds. He stated he didn't see supplemenation possible at his age. I honestly think my doctor didn't realize the wide variety of supplements available. I supplement my ds2 w/ calcium supplements from a local health food store specifically for children. Nothing is prefect mind you, the Dino Eggs are jellybeans, but I'll take the little added sugar over no calcium intake for the day. I also found liquid calcium flavored that I add to his juice at least once a day.
I do not understand why a doctor would be suggesting weaning, does he understand that the child will not get dairy milk if weaned? I think a lot of times doctors fail to look at the entire family dynamic and dietary restrictions.
If this mother has to go back in say a few weeks to have the dc checked, she should ask the doctor what he/she suggest she feed dc if she were to wean. And then when the ignorant doctors says milk, she can't state either an allergy or dietary restiction to dairy and then say now what?
Also encourage the mother to look at her dc's physical shape and size and the over all health of the child. Some children are pettite and are not going to be with in normal ranges on those "charts" ever. And they are completely healthy for who they are.
I think in general pediatricans are still very ignorant to breastfeed babies and children. And they expect that a child of 1 would be drinking cows milk at least 3 times a day and those growth charts may or may not have been updated to account for children who are bf past 6 mo old. I also think the growth charts in general are not accurate depictions of a child's health.
For example: A 2 yr old who eats pizza and drinks soda and rarely eats a veggie may be considered of normal weight and height where as a child who eats mostly veggies and fruits and still nurses might come in as below normal. And we all know that the child eating the veggies and fruit is in a much healthier state of being than the fastfood soda drinking 2 yr old!!!
I hope you share these post with her and she can be encouraged not to worry too much, but to continue nursing and possibly trying to give more full fat foods for snacks or meals verses the mainstream cheerios and gerber toddler snacks. And to look at the over all health issue and if her dc is just pettite or if there is a real problem. Although generally speaking a bf child is not likely to be having a serious problem at age 1 that would have been over looked until now.
