Hi hun
My son was lactose intolerant
It started when he was quite young, he had bad colic (I was breastfeeding) and a lady on here told me to try cutting out dairy out of my diet, so I did and within a few days, the colic was 10 times better. I didn't think anymore of it really, just kept dairy out of my diet.
During this time he was in hospital twice with dehydration. He had bad diarrhea and couldn't keep a lot down.
It got worse at 4 months when he started taking solids as well as breastmilk. The only thing I could give him that he would keep down was blended vegetables. I got in trouble off the health visitor because he was dropping down his percentile lines and not putting on weight (loosing it at one point) and she blamed me because I wasn't giving him a lot of dairy.
When I went back to work he was 8 months old and that's when it came to a head. We took him off breast milk completely and he went on to formula and ate the same diet the kids at nursery did. They keep notes at nursery of what the kids were eating, and also their pooing & weeing patterns. We got called into nursery a lot in the first few weeks because he would just lie there and scream in agony and then either be sick, or have a loose nappy. He was in so much pain with it. We sat down with nursery and eventually tied together that it was about 20 minutes after a bottle or portion of dairy (yoghurt/cheese) that he would turn poorly.
We took him straight to GP who did a stool sample for viruses but said there was no point checking for lactose intolerance, because it wouldn't be that. Samples came back clear and we were told it was probably some kind of bug. He was hospitalised again (two or three times) with dehydration and they suggested lactose intolerance. He was badly underweight because every day he wasn't keeping his food or milk down.
Eventually I walked into the Drs surgery with him, sat down and basically said "Im not moving until you test him for lactose intolerance". I took his slips from nursery and a record of his eating & nappy/being sick patterns and literally did not move from the spot until he agreed.
Suprise suprise - he was lactose intolerant. We think it may have been triggered by gastroenteritis he suffered at a few weeks old.
It took us a LONG time for him to be diagnosed, and a lot of pressure to the Drs. HVs always were telling me it was my fault, I wasnt feeding him properly etc and I put my poor boy through this for months
I feel horrible for it now. But how was I meant to know!!!
Dr didn't give us anything really, so we just switched his whole diet to lacto free (we used cow & gate lacto free formula) and we could see an improvement in days really.
When he is poorly now, it sends him a bit the same way, but on the whole he has been back on full dairy for a year roughly now.
If you do think your LO may be lactose intolerant you need to put your foot down for testing. I don't know why Drs don't seem to take it seriously.
Good luck hun xx
