For a safe and easy delivery for pregnant Mothers , I am providing some mantras.

In addition to this, one may vow to offer a bunch of Raw Bananas (Vaazhaith Thaar) to Thaayumanavar Swamy at Tiruchirapalli.
This vow may be fulfilled after Delivery by carrying the Vazzhaith Thaar in person up the steps and offer to the Lord Thaayumaanavar.

Hiring of people to carry this, is not recommended.
One may also pray to Karbharakshambigai at Thirukkarukavor for safe delivery( one may pray here for begetting a child), collect the oil they provide and
apply it on the stomach when the Labor starts.

Lord Shiva is reported to have attended the Labor of His Devotee and ensured safe delivery.
Shiva was worshipped by the demon ruler Tirisiran, hence Tiruchirappalli, Tirisirapuram etc. Also, since the three peaks here on this hill are occupied by Shiva, Parvati and Vinayaka, the name Tri-Shikharam or Tirisirapuram came into being. Legend has it that Shiva in the guise of a woman (mother) attended to the call of a devotee in labor, hence Matrubhuteswarar.
Tiruchirappalli is hailed as Dakshina Kailasam, as the hill is said to be 1 of the 3 pieces that flew off the Himalayas. in a fierce tussle between Adi Seshan the mythical snake and the Wind God Vayu. The other two are Triconamalee & Sree Kalahasti.
The Temple: This is a fascinating rock cut temple with several inscriptions from the Pallava and Imperial Chola period. This shrine houses Kangaala Moorthy, one of the 64 manifestations of Shiva. The approach to the temple is through a flight of covered stairs. Towards the end of the climb, the Tayumanavar temple is towards the West, and theUchipillayar temple – East.
There is a rock cut Pallava temple – Lalitankura Pallaveswaram in this hill temple complex. with several inscriptions here attributed to Mahendravarma Pallavan. In addition the Cholas, the Vijayanagar rulers and the Nayaks of Madurai have made extensive contributions here. The two storeyed Taayumaanavar temple, built on (in) a hill is a masterpiece of construction. The Chittira Mandapam houses a granite chain with nine loops.
Festivals: Six worship services are offered each day here. This well endowed temple celebrates the annual Bhrammotsavam in Chittirai. Aadi Pooram and the float festival in Panguni are also of significance here.
