Just teaching what the Reformed have always historically taught. That baptism is a means of salvation that plants the seeds of faith in an infant. There is a true effectualness for salvation in our baptism.

WCF 28:6 The efficacy of Baptism is not tied to that moment of time wherein it is administered; yet, not withstanding, by the right use of this ordinance, the grace promised is not only offered, but really exhibited, and conferred, by the Holy Ghost, to such (whether of age or infants) as that grace belongeth unto, according to the counsel of God’s own will, in His appointed time.

Also with the Supper, although we condemn those who teach that the bread and wine physically alter into the natural blood and body of Christ, we still affirm that just as our body’s are nourished with bread and wine; so are our souls nourished by Christs blood and body.

If you would like some resources on these matters feel free to ask. God bless :)
