- 1Baby’s Development. Your baby gaining fat, making their skin less wrinkled, while the brain and nervous system mature. Hearing is improving—your baby may even respond to your voice. Movement patterns are becoming more noticeable, often when you’re resting.
- 2Bodily Changes & Symptoms. Your uterus is growing and may cause digestive issues, constipation, or reflux. Common symptoms include sciatica, pelvic pain, leg cramps, and occasional Braxton Hicks contractions. Fundal height is usually around 25 cm at this stage.
- 3Health & Wellness. Stay hydrated, eat fiber-rich foods, and walk or stretch to ease constipation and cramps. Small, frequent meals and avoiding trigger foods can reduce heartburn. Use warmth, ice, or gentle yoga to help with aches, and always check with your provider before taking any medications.
- 4Tips & To-Dos. Discuss labor pain relief options and consider taking childbirth or parenting classes. Begin planning the nursery and baby gear, and review safe sleep practices for your little one’s arrival. Your provider may recommend glucose screening soon and can guide you on when to start tracking fetal movements.
Checklist for week 25
