Having no knowledge on the issue is better then having partial knowledge...
Common "People" are stealth. No denying in that but that's a design feature don't make sound like a bug. This is one of the reason why Allah Taa'la created a flawless system of "SAZA and JAZA".
Plus being stealth is lot better then ADVERTISING your un-Islamic practices and then quoting prophet Mohammad (SA, PBUH) to justify them without having the full grasp of the subject matter...(sounds like a trait of a traditional common Mullah of a corner mosque in pakistan).
You are not alone, we lost 5 children, 4 in still-birth and miscarriages and one in an accident when he was few months old before Allah Taa'lah blessed us with 3 most beautiful angels. Sad but common in life.
Adoption has nothing to do with what you quoted above. If you take what Prophet Mohammad (SA, PBUH) said as an example or permission of adoption in Islam, it would be a direct conflict with what Allah said in Quran (reference follows) and prophet Mohammad (SA, PBUH) never said anything that conflicts with Quran. He (SA, PBUH) was mistake free, his sayings were error free. PERIOD.
According to the Quran, one cannot become a person's real son merely by virtue of a declaration; Allaah Says (what means):
"...And He * has not made your claimed * sons your [true] sons. That is [merely] your saying by your mouths, but Allaah says the truth, and He guides to the [right] way. Call them * by [the names of] their fathers; it is more just in the sight of Allaah. But if you do not know their fathers, they are your brothers in religion…" [Quran 33: 4-5]
This shows that the declaration of adoption does not change realities, alter facts, or make a stranger a relative, or an adopted child a son or daughter. A mere verbal expression or figure of speech cannot make the blood of a man run through the veins of the adopted child, produce natural feelings of affection found in normal parent-child relationships, or transfer the genetic characteristics, or physical, mental, or psychological traits.

By adopting someone's child as one's own, the rightful and deserving heirs to the property of a man are deprived of their shares. Hence, Islam has made it Haraam (forbidden) for a father to deprive his natural children of inheritance. Allaah has established the distribution of inheritance in order to give each eligible person his or her share. In matters of inheritance, the Quran does not recognise any claim except those based on relationship through blood and marriage. The Quran stipulates (what means):
"And those who believed after [the initial emigration] and emigrated and fought with you – they are of you. But those of [blood] relationship are more entitled [to inheritance] in the decree of Allaah. Indeed, Allaah is knowing of all things." [Quran 8:75]
There are also numerous Quranic verses that support the act of taking care of orphans and enough cannot be said about how pleased Allaah is with this noble and charitable act, see: [Quran: 2:220; 4:2; 4:6; 4:10; 4:127; 17:34]
Taking care of orphans is a completely different form of adoption, which is not prohibited by Islam - that is, when a man brings home an orphan and wants to raise, educate, and treat him as his own child. In this case, he protects, feeds, clothes, teaches, and loves the child as his own without attributing the child to himself, nor does he give him or her the rights which the Sharee'ah (Islamic Law) reserves for his natural children.
This is a meritorious and noteworthy act in Islam, and the man who does it will be rewarded by being admitted to Paradise. Prophet Muhammad once said: "I and the one who raises an orphan, will be like these two in Paradise (and he pointed his middle and index fingers)"

The point is to not get stuck in semantics, adoption as in jahliya is one thing, raising an orphan as a guardian is another. The term adoption is used because no one has suggested an alternative proper term. lets use the term fostering then perhaps.
the reasons given about raising a na merham at home and all that jazz are there whether you have 'adopted' a child in a jahliya sense or are raising them in an islamic manner.
the issue also is that people just go with a statement like. adoption is not allowed, and then go into issues like mehram and inheritance, and thus give the wrong impression that islam discourages anyone raising an orphan in their home. That paints a rather wrong picture.
I dont have any unislamic practices as far as it comes to the kids, them being adopted is common and public knowledge, my siblings and parents have already gifted their share of inheritance legally to these kids in the event I kick the bucket, and that the kids call me daddy is something discussed and approved by scholars because the kids are too young to understand anything and it has psychological issues if everyone else has a mama and daddy and they dont, as they grow older and as they learn more about the fact that we are not blood relatives, they can choose to call me whatever.*
