Breastfeeding and Bottle-Feeding Fundamentals
At 20 weeks, your baby’s feeding habits are becoming more established.
Whether you’re breastfeeding or bottle-feeding, consistency is key.
We recommend sticking to a schedule that works for both you and your first child or baby.
Breastfeeding mamas, don’t forget to take care of the baby’s shower yourselves too! Stay hydrated and keep those healthy snacks handy.
For our pregnant bottle-feeding friends, make sure you’re using the right nipple size to feed your baby to avoid overfeeding or frustration.
Remember, every baby’s growth now is different. Some might expect to be guzzling down 6-8 ounces per feeding, while others might prefer smaller, more frequent meals.
Trust your instincts and your baby’s cues.

Crafting the Perfect Bedtime Ritual

Start the night with a warm bath to get the skin and those tiny muscles relaxed. Then, slip into comfy PJs and snuggle up for a bedtime story.
We love using soft lighting and playing some gentle tunes to set the mood.
Don’t forget a final feeding and diaper change before lights out.
Consistency is key here!
Stick to the same order of events each night, and your baby’s lungs and body will start to recognize it’s time to wind down.

Swaddling your baby is like a magical hug that can help your 20-week-old child feel secure and sleep better.
But if making sounds, your cute little wiggle worm is starting to begin to roll, it’s time to graduate to a sleep sack.
Sleep sacks are awesome because they keep baby warm without loose blankets.
Plus, they come in the cutest designs – who doesn’t love a tiny astronaut or mermaid?
Pro tip: Have a backup ready in case of midnight diaper blowouts. Trust us, you’ll thank us later!

Playtime Learning: Infant Toys and Games
Playtime isn’t just fun – it’s a crucial part of your baby’s development at 20 weeks.
We love seeing those tiny arms and hands grab everything in sight!
Colorful toys and games are perfect for sparking curiosity and learning.
Try these ideas:
Rattles and shakers for sound exploration
Soft blocks for grasping practice
Textured toys for sensory stimulation
Peek-a-boo is a classic game that never gets old.
It helps teach object permanence – the idea that things still exist even when out of sight.

Remember, everyday objects can be learning tools too.
A plastic cup becomes a drum, and a cardboard box transforms into a fort.
