Interrupting Tawaf of `Umrah

Q: I am a Saudi citizen who resides in Jeddah. I went to perform `Umrah (lesser pilgrimage) along with my wife (Part No. 11; Page No. 322) and a baby that was being breastfed. This was on the twenty-seventh of the last blessed Ramadan. We were faced by a huge crowd and my wife was lost after we finished the first three rounds of Tawaf (circumambulation of the Ka`bah). My breastfed baby remained with me and I stopped my Tawaf and continued looking for my wife as she was not familiar with Makkah and did not know the rituals of `Umrah. The situation became more complicated and I felt bewildered because of my breastfed baby who was crying and my wife who was lost. Thus, I left Al-Haram (the Sacred Mosque in Makkah) and Makkah and went to Jeddah. I left the breastfed baby at my neighbor's place in Jeddah and returned to Makkah to look for my wife. I contacted the police and finally found my wife there by the end of the night. The time was very tight as Suhur (pre-dawn meal before the Fast) was approaching and our breastfed baby, whose mother was greatly worried about him, was still in Jeddah. I also felt tired at that time. Finally, we traveled to Jeddah without completing our `Umrah. Is it obligatory on us to make up for the `Umrah, do any Kaffarah (expiation), or does Islam pardon us because of the problem we had? It may be worthy to mention that this was not our first `Umrah for we had performed `Umrah more than once before. I would also like to inform your Eminence that we conditioned upon entering into Ihram (ritual state for Hajj and `Umrah) that we would abandon `Umrah when Allah (Exalted be He) would detain us; is this considered a Mashru` (Islamically acceptable) detention or not?
