I sat down with my wife, Crystal Sikes, and had one of those honest conversations parents need to hear. She just finished her fourth trimester with baby Hazen, is balancing a spirited three-year-old, and is slowly getting back into heavy training. Her story is practical, messy, and full of lessons that helped me rethink how I coach and live my life around family and fitness.
The fourth trimester covers roughly the first 12 weeks after birth. It is a time for recovery, bonding, and major adjustments. Crystal reminded me that people often forget postpartum is its own season. New moms are healing, feeding, managing hormones, and almost always running on very little sleep.
Early on, Hazen cried nonstop. He had plenty of volume in milk but wasn't gaining well. The doctor asked the simple question: What are you eating? Crystal hadn't been prioritizing food. She was busy with two kids, healing, and survival mode. Once she intentionally increased her calories and focused on nutrient-dense meals, the baby started gaining weight rapidly.
If the breastfeeding baby seems constantly hungry, look at the mother's intake first. More quality calories and consistent meals can change everything.
Crystal's recovery took longer this time. She pushed through, cared for a toddler, and didn't rest enough. She works with pelvic floor therapy and a midwife, and she's honest about how healing can be delayed when you never truly rest.
Small wins to track: walking pain-free, pelvic floor therapy progress, and being able to perform compound lifts without discomfort. Those are better markers than the scale in months one or two.
Training after a baby isn't all or nothing. Crystal started with a primary compound movement in the morning and accessory work three times a week with a friend. Progress looked like five sets working up to five reps at 135 pounds on squat day. That was a win.
We built a garage gym so workouts could happen early while the house is quiet. When training with a baby and a toddler, the approach is flexible: do something, be consistent, and prioritize big compound lifts gradually.
Rigel, the three-year-old, is not jealous, but he does seek attention. Crystal and I talk about offering structure, chores, and consistent time to avoid attention-seeking misbehavior. Little responsibilities like chicken chores or library trips help. He's into books, kinetic sand, and being outdoors. Simple outlets that keep him engaged.
Crystal went off social media for over a month. She found that putting the phone down made her more present with her kids. She read books, had better conversations, and didn't default to doomscrolling while nursing. The result was less stress and more meaningful moments.
Practical Habits You Can Use Now
As a coach and dad, I want fitness plans that fit real life. Crystal's approach is honest: feed the body, protect the recovery, and build training habits that respect family chaos. That's how long-term progress happens.
Q: How long is the fourth trimester?
A: The fourth trimester is typically about 12 weeks after birth. It is focused on physical healing, establishing feeding, and bonding with the baby.
Q: What if the baby seems hungry even with plenty of milk?
A: Check the mother's nutrition and calorie intake first. Increasing nutrient-dense calories often raises milk fat and helps the baby gain weight.
Q: When is it safe to lift heavy again?
A: Work with a pelvic floor therapist and your care provider. Start with one compound movement and progress slowly. If movements feel good and no pain appears, you can gradually increase the load.
Q: How do you manage a toddler and a newborn?
A: Structure, simple chores, and consistent attention help. Use play-based activities and schedule shared quiet time. Ask for help when you can to catch up on rest and nutrition.
