Could I please hear from anyone trialling the fs diet with a baby? How did you work out the severity and presence of symptoms? We have an appointment with a dietician to (hopefully!!) work out the cause of our 9.5 month old being awake and uncomfortable after dinner for up to 8 hours sometimes. The allergist suggested amines and salicylates since the problem foods are all listed as high or very high – Cath

My little one was confirmed with a salicylate intolerance at 10 months after a strict 6 week elimination diet. My suggestion would be to have a food dairy to track all food and fluid intake and reactions. I specifically tracked sleeping and stool as well as these were big ticket items for us. I would also recommend from my experience starting at the beginning with the elimination diet then introducing new foods in a timeframe agreed with dietician and your baby’s symptoms. Be flexible though as it can change. I still track 14 months on! – Laura

We started when my daughter was 3 months old. She was solely breastfed so meant I needed to do it. We tested me, and she was tested through my milk at 9 months. We did more testing when she was about 3. Early tests gave us back salicylates – Anne

We started dabbling with the diet at that age but didn’t commit fully until just after 1yr. After 6 weeks on failsafe our boy finally started to relax, play independently and sleep through. Good luck with your bub! – Carol

I went through this when my son was 6 months old. He wouldn't settle to sleep, had eczema issues, was constipated despite being breastfed and seemed almost hyperactive. The elimination diet was probably harder for me as I was breastfeeding so had to do it as well, at six months he hadn't eaten a lot of solids. But by day 3 we went through a bad withdrawal phase and by day ten my son slept 5+hrs for the first time in 4 months. He is now a much happier healthier child (and he sleeps!), and is slowly building his tolerance levels so we are introducing new foods. He is now 16 months and is starting to tolerate moderate salicylates and amines. The elimination showed sensitivities to amines, glutamate s and salicylate so we are on a long journey but his recent improvements have given me hope. The downsides of this diet were really for me. I was very stressed and sleep deprived when I started it. It contributed to my milk supply drying up and also impacted on my mental health which to be fair was not in good shape when I started. I lost 5kg unintentionally and was so bored with the food I lost interest in eating. I wish I had stopped breastfeeding to be honest earlier so I didn't put myself through it. No one warned me that my milk supply could be threatened but I also know it was likely a combination of things. I was however grateful to have such a good medical team behind me even if it did mean travelling 3 hrs initially. Best wishes to you and your child! - Cassie

We started elimination levels on my LO when he was 1. I was still BFing, so did it too. Amazing improvement in a few days. We trialed foods in my diet (ie through my milk) before trialing the same foods on him directly. I strongly suggest you keep a detailed food diary that includes anything that goes into your mouth or his as well as his symptoms (stool consistency/mucous/blood, temperature (if unwell), vomiting, diorhhea etc) & anything important that may have happened that day (eg went to day care, birthday party). This includes drinks/liquids as well as medications & brands of food. I discovered when we changed brands on one item we saw a reaction. Also, it meant if my LO needed pain relief, the kiddy Panadol syrups were not ok, so we need to buy the tablet form (without preservatives) & crush the tablet & give a portion of the tablet based on his weight (I recommend talking to your pharmacist about suitable dose). We found similar with Amoxil & other meds. Good luck, mumma - Sarah

My daughter was the same, tummy aches didn't sleep and it was eggs. She was breast fed so even if I ate eggs she was affected – Jen

We started FS when bub was about 12 weeks old 😬 He was breastfed and suffered extreme gas and silent reflux and was either being fed or screaming, very rarely sleeping. It was difficult to work through and I made many mistakes unfortunately. We kept a strict food diary which helped me go back and analyse things as needed.

We saw improvement after a few months when I started to get the elimination stuff right.... his main trigger is salicylates so he’s still relatively low sals at nearly 3. I must admit it was a relief when we weaned at 2.5 and I was able to eat “normal” foods again.

We found challenges very difficult because with young children there is always something else going on - it took us until he was 18 months to get through them. Since challenging we’ve been able to reintroduce amines, soy and dairy (gluten was never an issue for us).

I love the RPA handbook for a quick easy reference guide for what he can and cannot eat. I’ve also used it to explain to family what we’re doing with diet because they didn’t understand and we’re quite critical.

My other tip as they get older is to continue to look out for behavioural manifestation of reactions. Our sons tummy symptoms have lessened but the behavioural symptoms have significantly increased - Karen

(Sue comment: make sure your dietitian is familiar with RPAH elimination diet.  See supportive dietitians)
