Common Custody Schedules in New Mexico: Age-by-Age Guide

Picking a custody schedule is not about which arrangement sounds fairest. New Mexico courts evaluate proposed schedules against age-appropriate developmental guidelines published by the Second Judicial District Court Clinic. A schedule that works perfectly for a ten-year-old can be developmentally harmful for a two-year-old.

Infants (Birth to 1 Year)

Overnights are not automatic for infants. The Court Clinic guidelines recommend:

• Minimally involved parent: 2-4 hours per day, 3 non-consecutive days per week. No overnights. After 4-5 months of consistent contact, graduate to 4-8 hours per day.
• Moderately involved parent: 3-4 visits of 3-6 hours per week. Single overnights may begin after 4-5 months if the baby shows secure attachment to both parents.
• Very involved parent: Frequent short intervals (every other day for 4-8 hours). Single overnights can happen weekly, progressing to a maximum of 2 non-consecutive overnights per week.

The guiding principle is maintaining the infant's attachment to their primary caregiver while building a bond with the other parent.

Toddlers (1 to 3 Years)

Separations longer than 3 days are developmentally problematic at this stage. Schedules should keep contact frequent:

• 2-2-3 rotation: Parent A has Monday-Tuesday, Parent B has Wednesday-Thursday, weekends alternate. The child never goes more than 2-3 days without seeing each parent.
• Modified 2-2-3: Same structure but with shorter blocks (daytime only) transitioning to overnights over several months.

The Court Clinic guidelines emphasize that toddler overnight readiness depends on the child's temperament, the quality of both home environments, and consistent bedtime routines at each house.

Preschool (3 to 5 Years)

Children at this age can handle longer separations and benefit from predictable routines:

• 2-2-3 with full overnights: The standard shared schedule for preschoolers with two involved parents.
• 5-2-2-5: Parent A always has Monday-Tuesday, Parent B always has Wednesday-Thursday, weekends alternate. More predictable than 2-2-3 because midweek days never change.
• 4/3 split: One parent has Thursday through Sunday, the other has Monday through Wednesday. Simple and consistent.

For preschoolers with one minimally involved parent, the Court Clinic recommends starting with 4-8 hours, 3 times per week, progressing to full overnights after several months.

School-Age (5 to 12 Years)

School-age children can manage longer blocks and benefit from consistency around the school week:

• Alternating weeks (7/7): One full week with each parent. Exchanges typically happen Friday after school. Works well for cooperative parents who live near the same school.
• 5-2-2-5: Provides consistent school-week structure while sharing weekends. Preferred in high-conflict cases because exchanges are predictable and routine.
• 2-2-3: Still viable but involves more transitions per week than some families prefer.

For school-age children with a minimally involved parent, the court typically starts with every-other-weekend visits plus one midweek dinner or overnight, gradually increasing time as the relationship strengthens.

Teenagers (13 to 18 Years)

Teenage schedules need flexibility. Extracurriculars, part-time jobs, and social lives make rigid schedules impractical. Most courts default to:

• Alternating weeks (7/7) with flexibility for the teenager to adjust based on school and social commitments.
• Longer blocks (two weeks on, two weeks off) for parents who live farther apart.

The key consideration: teenagers 14 and older can express their custody preference to the judge, and courts give that preference significant weight under NMSA 1978 Section 40-4-9(B).

Matching Your Schedule to the Support Worksheet

Remember the 128-overnight threshold. If each parent has at least 128 overnights per year, child support is calculated under Worksheet B (with the 1.5x multiplier). Below 128 overnights, Worksheet A applies. Count your proposed schedule carefully before presenting it.

The New Mexico Child Custody & Parenting Plan Guide includes printable schedule templates for each arrangement, overnight count calculators, and age-specific examples that match the Court Clinic guidelines.
