1- Who makes foetus laugh and weep ?
In a very significant verse in surat Al-Najm Allah says about him self: "And that He it is who maketh laugh, and maketh weep," (Quran 53:43)
This verse contains a very nice scientific indication about the lately-discovered fact that foetus has facial expressions while he is in his mother's womb, without being taught to do so.
Im sorry. But number 1 that is not a miracle but natural body movements in the womb. Babies grab their feet, suck their thumbs, etc... Thats not a miracle.
