As you will be aware, the public health restrictions at level 5 of the Government's Framework Resilience and Recovery 2020-2021: Plan for Living with Covid-19 will remain in place until 5th April 2021, when a further review will be conducted. The framework continues to provide an appropriate mechanism to guide decision-making, and it will continue to be supplemented by more detailed sectoral guidance in relation to measures that apply at each level of the framework.
On 23 February, the Government published Covid-19 Resilience & Recovery 2021: The Path Ahead which sets out how in-school education and childcare services will be reinstated in a phased manner from 1 March, with staggered return throughout March to be concluded after the Easter break on 12 April.

At Level 5, people are asked to stay at home as much as possible unless they have a "reasonable excuse" for leaving.
The Regulations providing for these measures are set out in S.I. No. 701 of 2020 and S.I. 29 of 2021. Regulation 4. of SI 701 sets out a non-exhaustive list of reasonable excuses for leaving one’s home. This non-exhaustive list includes at 4. (2) (w) in the case of a person who is part of a paired household, to travel to an event in a dwelling in accordance with Regulation 5.
Regulation 6. of SI 701 of 2020 sets out the meaning for paired households. Further clarification on support bubbles (paired households) is provided on gov.ie:- https://www.gov.ie/en/publication/3516d-support-bubbles/
