Yes. Hanumāna is worshipped across India in several forms, even in infant form also.
1. Bālājī Hanumāna Mandira, Mehandīpura (Rājasthāna)
- As per their official site, in this temple bālājī Hanumāna is consecrated and worshipped in his child (bâla - बाल स्वरुप) form, and thus known as Bālājī Hanumāna.
The temple is considered as famous exorcism center too, for people afflicted with evil beings
2. Hanumānagaḍhī (Ayodhya, UP)
- One of the most famous temple is found in the the city of God Râma - Ayodhya itself, in the present day state of Uttar Pradesh, known as Hanumānagaḍhī (हनुमानगढ़ी).
Quoting from the official tourist guide of the Uttar Pradesh government -
हनुमान गढ़ी
Hanumāna-gaḍhī Temple
पवनपुत्र हनुमान को समर्पित यहाँ मंदिर अयोध्या रेलवे स्टेशन से १ किमी
दूरी पर स्थित है, इस मंदिर का निर्माण विक्रमादिय द्वारा करवाया गया था
जो आज हनुमान गढ़ी के नाम से प्रसिद्ध है| ऐसी मान्यता है की पवनपुत्र
हनुमान यहाँ रहते हुए कोतवाल के रूप में अयोध्या की रक्षा करते हैं|
मंदिर के प्रांगन में माता अंजनी के गोद में बैठे बाल हनुमान को दर्शाया
गया है|
Summarized English Translation of the above:
This temple is said to have been constructed by King Vikramaditya.
The religious belief associated with this temple is that god Hanumāna, residing in the temple protects the city of Ayodhya as the kotavāla (police).
In the temple's premises Hanumāna is depicted in his infant form, sitting on his mother Añjanā's lap.
However, the main idol in the Sanctum Santorum is of the Adult form of Hanumāna.
(currently I cannot locate any scriptural references for this though).
