He obviously hasn’t done his research because where on earth is it recommended to wait until baby has teeth (which might I add can be way past a year old anyway!). The recommended advice is 6 months when baby’s digestive system is ready. Other signs Include ; sitting up (good neck control they don’t have to be able to fully support their trunk) , hand eye coordination and tongue thrust is no longer present. I would be explaining the longer you leave it the more likely they are to develop a reaction towards food. If he doesn’t like it in my opinion I’d just go for it because that sounds absolutely ridiculous in my opinion xx
Maybe suggest he actually speak to a health professional to get some proper information, as he seems to have misinformation. GP, health visitor etc would be able to.put him on the right track. Happy to share some vids of my 7 month old chwing down full meals of it helps xxx
I'd honestly want to know what research he's been doing because my understanding is that by a year old her nutrition should be from food alone? So if you only start weaning then she won't be taking in enough food as it will take her time to get used to foods and learn to swallow and chew etc. I'd ask him to show you the research that says you should wait until a year old to wean because everything I read said 6 months. I assume he's read that their main nutrition is still from breast/formula milk until one and assumed this means no solids because from a quick Google I can't find anywhere saying to wait until after 1. Show him your own research that contradicts what he's saying and then start weaning her. You've done it before, you know what you're doing.

I would show him research that says differently. After six months, breast milk is not a sufficient source of iron, for example. In terms of teeth, babies can chew very well with their gums, so maybe show him research on that too.
