Hi Zahra,
Just keep monitoring his hb,since he is not six months old,one can not be sure ,he can be a thal major and he can be a thal intermedia,when he is six months old you can repeat hb electrophoresis to get the clear picture,if he is an intermedia,he might not need transfusions if his hb maintains.and you'll be able to try hb F inducers,which can help maintain his hb and avoid transfusions.If his hb keeps hovering between 7-8 he might br an intermedia,to make sure,you can get DNA testing.
Keep sharing.
Zaini.
