Marrying the daughter of a woman who breastfed one

Q: A child drank milk from a woman. Later vomited it all out. Would it be haram for this boy to marry this womans daughter. The families are very close to each other. (I said no, but they said, the boy vomit it out. i said, there is a possibility that some stayed in the stomach.) They want a response from a mufti saheb. To complicate it shiek Usaymeen of saudi arabia in his fatwa kitab said so long as it is not beyond 5 sucklings it is ok, this maybe the hanabila view. The person asking is hanafee)

The appearance of Dajjaal and shortage of food

Q: I have a question regarding the appearance of the dajjal and shortage of food. In one report it says before his arrival, there will be shortage of food and drinks for 3 years (musnad ahmed).

However, in another hadith it says under the Mahdi, there shall be abundance of food to such an extent a man will say "mahdi, give me" and he shall reply "take it".

Now my confusion is that the dajjal is to emerge during the mahdi's time, so how to reconcile the two situations?
