Infinito Mosquito
Chain verbs, describe what's happening, and place pronouns without freezing mid-sentence.
Spanish reaches for the infinitive where English uses -ing: after every preposition (antes de salir, sin decir nada, al llegar) and as a subject — Viajar es mi pasión, never a gerund there. The gerund (-ando/-iendo) is strictly for action in progress: Está hablando por teléfono. And with two-verb chains, pronouns have exactly two valid homes — before the conjugated verb or attached to the infinitive or gerund: Lo quiero comprar = Quiero comprarlo, Lo estoy leyendo = Estoy leyéndolo — both fully correct, never in the middle.
Below: the chain frames with their phrases, the English -ing traps, the accent rule for attached pronouns — and how you make both positions automatic by speaking, not by circling answers.

No pronoun-attachment drills on a screen — in the Infinito Mosquito lessons you build the chains out loud and Carla catches what English smuggles in. She springs the classic trap — say "Traveling is my passion" — and you land on Viajar es mi pasión, infinitive, not gerund. Then she asks about your plans and your week, and the frames stack naturally: Vamos a salir a cenar esta noche, Acabo de hablar con ella — with you choosing, in real time, whether the pronoun goes in front or rides attached: Te lo quiero dar or Quiero dártelo.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.

Quick answers
After any preposition and as a noun/subject — exactly where English uses -ing: antes de salir (before leaving), Estudio mucho para aprobar el examen, Viajar es mi pasión (traveling is my passion).
Two positions, both correct: before the conjugated verb (Me tengo que levantar temprano) or attached to the infinitive (Tengo que levantarme temprano). Never between the two verbs. Double pronouns travel together: Te lo quiero dar = Quiero dártelo.
-ar verbs → -ando (hablando); -er/-ir verbs → -iendo (comiendo, viviendo). It pairs with estar and seguir for ongoing action: Sigue lloviendo desde esta mañana.
Attaching a pronoun to a gerund adds a syllable, so a written accent keeps the stress in place: Estoy leyéndolo, Está duchándose. Put the pronoun before the verb instead and no accent is needed: Lo estoy leyendo, Se está duchando.
No — Estoy comiendo means right now, not later. For plans, chain with ir a + infinitive: Vamos a salir a cenar esta noche.
