Pope says Heaven apart from Christian faith?

To address your questions in order.

Does the Catholic church officially recognize baptizing ones children as a good work that qualifies you for salvation?

Not by itself. Heck, as a parent, the Church more or less expects if of you. If you don't have your children baptized, you're doing it wrong. That's a very terse summary of the Church's position. (I speak as both a Catholic and a parent).

As for "what qualifies for salvation" that's a huge topic and a slightly loaded question. The nuts and bolts of it is Baptism into the Church; remaining in communion with Christ/The Church/God; remaining free of the stain of mortal sin (and repenting from such sin and returning via the sacrament of reconciliation when it happens); those three are an incredibly brief summary of what the Church teaches as the path to salvation. It does not do the topic justice. And while you are at it, don't forget prayer and selfless service in His name. (Aside: when Jesus told his disciples to "pick up your cross and follow me" the subtext of that message was not "this is gonna be easy." There is no Easy Button).

If the church does not recognize this, is Francis speaking apart from the teachings of the church. Is that allowed?

While The Holy Father is being a little glib (and IMO sloppy) in his public relations appearance there, he is speaking to his audience: children. It is worthwhile to consider the context and setting of his remarks. That said:

• A document issued from Vatican II, Lumen Gentium, presents an offer of hope (beyond general human understanding) of salvation due to God's mercy. It is unknowable when God's mercy enters into such a path to salvation. This was controversial when it came out, and remains a topic of some disagreement. (It is not dogma, and as our friend @Geremia here at Christianity.SE might remind us, it makes statements at odds with the pronouncement at the Council of Trent that there is no salvation outside of the Church; a pronouncement that has not been repealed). You can, however, view his recent remark as being consistent with this article.

  {Extracted from Lumen Gentium article 16}
  Those also can attain to salvation who through no fault of their own do not know the Gospel of Christ or His Church, yet sincerely seek God and moved by grace strive by their deeds to do His will as it is known to them through the dictates of conscience. Nor does Divine Providence deny the helps necessary for salvation to those who, without blame on their part, have not yet arrived at an explicit knowledge of God and with His grace strive to live a good life. Whatever good or truth is found amongst them is looked upon by the Church as a preparation for the Gospel. She knows that it is given by Him who enlightens all men so that they may finally have life. But often men, deceived by the Evil One, have become vain in their reasonings and have exchanged the truth of God for a lie, serving the creature rather than the Creator. Or some there are who, living and dying in this world without God, are exposed to final despair. Wherefore to promote the glory of God and procure the salvation of all of these, and mindful of the command of the Lord, "Preach the Gospel to every creature", the Church fosters the missions with care and attention.

  Is it allowed? Well, he's the Pope. What he's supposed to do is lead the church. He is also human, and can be careless. Nobody but his own conscience can govern his decisions on what he says. (As my wife has asked me to stop making comments about this particular Pope, that's as far as I'll go).

Is it official now just because he has said such?

No. This is not an ex cathedra pronouncement. There is a particular form for making such statements in matters of faith and morals. Such utterances are rare; the last one I recall covered the Assumption of the Virgin Mary. That was the dogma explicitly conveyed in 1950, written/issued by Pope Pius XII on November 1, 1950 in his Encyclical Munificentissimus Deus. This off hand remark was no encyclical, nor any other form of ex cathedra utterance.

Is Universalism accepted by Catholics

That is a separate question, please ask it separately.
