i do think you could get further medical advice for his gut issues.
just to check for food intolences.
i dont think you should worry too much about food at 6 months. certainly this is the best time, and the idea of weaning early than that is not something to do for those with allergy problems.
without food are his bowel movements normal?
are they abnormal with solid food?
mucasy/acid or odd looking?
certainly would be frequent as he is still on a high liquid diet.
i wouldnt purree food, i would give him soft finger foods, and just let him play with them and explore himself.
there is not mad rush to get a lot of solid food in him, tastes single foods , in small amounts, will slowly build up over time.
if he eats any food his bowel movements will change.
do you think he is in great pain? esp at night, which does/can happen with food intolerence.
is he in pain when passing stools?
or after eating with upper stomach issues?
are you giving one food at a time?
i wouldnt bother with baby rice, nasty glue type stuff. but thats just my own personal views on packet stuff.
is he happy to try sweet veg and fruit?
intolerence in babies has two types,
the milk protein irritates the valve at the top of the stomach, causing it to not work very effciently. hence the vomiting, and realise of stomach acid irritating gut lining, also food is not digested in tummy, as ratio of digestive fluid is disturbed and milk not digested properly. this causes the gut damage.
these children have disturbed sleep patterns because of gut pain, and when laid flat on back to sleep, causes increased tummy pain.
lots of babies are spitters and vomit, some do this normally and develop well, doctors are not interested in 'happy' spitters, just the misrable , thin , exhausted ones!
the milk protien can cause a problem at the other end of the infant, irritating the lining of the anus and lower bowel.
food will have been digested normally ,so stools passed will look normal. however, as there are more nerve endings in the bowel than brain, the baby is in complete agony when passing stools.
recommeded that infants are on fully changed formula for at least 6--10 weeks before any complete change is noted, as gut takes a long time to heal, as its continually used.
partially changed formulas can work well for some infants, perhaps after gut has healed and digestion works well, but all this is indivdual, as intolerence levels are different for all.
what symptoms did your baby first show?
any of this remotely helpful?
