He-Boy Chronicles

"Though jurists have unanimously agreed that a pregnant or a suckling woman who apprehends harms to her embryo or her new-born child is allowed to abstain from fasting, they have disagreed as to whether she must make up for the fast days she missed later, or feed one poor person for each day she missed or both. Ibn `Umar and Ibn `Abbas maintain that she is to feed poor people equal in number to the fast days she missed. The majority of scholars are of the view that she must make up for the fast days she missed. Others yet hold that she is to do both. It seems to me that only feeding the poor is enough on its own for a woman who is constantly either pregnant or suckling, so that she has not got an opportunity to make up for the fast days she missed. So it may be the case that a woman is pregnant this year and a suckling mother the next and pregnant again the following year, and so on. She is therefore unable to make up for the fast days on which she refrained from fasting. So if she is commanded to make up for those days, she will have to fast for several years incessantly, which is definitely going to be difficult, and Allah does not want His servants to suffer hardships." - Islam Online

Confusing steer online... it really is hard to figure out which scholars are right and really know what Allah's will is. I'm googling to see if there is anything in the Quran which can help.

Here goes:

Like most other injunctions of Islam those relating to fasting were revealed gradually. In the beginning the Prophet had instructed the Muslims to fast three days in every month, though this was not obligatory. When the injunction in the present verse was later revealed in 2 A.H., a degree of relaxation was introduced: it was stipulated that those who did not fast despite their capacity to endure it were obliged to feed one poor person as an expiation for each day of obligatory fasting missed (see verse 184). Another injunction was revealed later (see verse 185) and here the relaxation in respect of able-bodied persons was revoked. However, for the sick, the traveler, the pregnant, the breast-feeding women and the aged who could not endure fasting, the relaxation was retained.
