For those who struggle. .. here are few tips I've picked up in 3 years of feeding therapy! My daughter has been in feeding therapy v since her first heart surgery ...using bottles. .through solids and still continues.
If you can find an SOS speech therapist or feeding group in your area do the course. Firstly the part for parents (this helps you understand how eating etc actually works) and then later. .if they offer the group sessions take your child.
-sensory play before food (playdough, magic sand or gross motor stuff like jumping on a trampoline etc). I often would set my daughter up in her high chair with playdough...so it would be a non threatening situation first...plus sensory play.
I would put all the foods out on offer at same time. And didn't care what order she ate them in.
Eg. Don't offer 'sweets'/desserts last. So I'd put out 3 or 4 things. Maybe chicken, cheese, strawberries and custard. She could eat or play. If she tasted or touched that was a win. Lots of praise.
Honestly this was tedious.... very tedious. Often leaving me in tears. And took a long time. Eg 20 minutes of sensory play. .then often an hour just trying to get her to taste. Plus after would be more sensory play.
I did this for probably 10 months to a year. My whole day was around it.
She has been ng fed and was on the list to have a Peg feed put in (tube through abdomen wall straight into tummy). Most children with her syndrome don't eat orally at all. Ever.
I really was desperate to give her some normality around food.
However..this process worked with lots of support from speech therapist etc. And she eats. Not a huge range of food. .but some. And there are of course days when she refuses all the things she usually doesn't!
But I really credit the SOS (sequential oral sensory) process and group/speech feeding sessions.
For mealtimes I often put out just a tasting plate. Sometimes at the table sometimes just in the floor and I let her graze. I always have at least one familiar food on the plate.
Sorry for the long post. This is what has worked for us. It's been an intensive full on road. But she's almost 3 and half and we've had a lot of wins and gains. She still doesn't eat enough to warrant removing pediasure but that's fine with me.
