"I have a good feeling about this month," Heather added before ending her string of mom and baby snaps with an adorable, crying Tristan laying on a "Love you to the moon and back" mat.

Heather has openly shared details of her new life as a mother since welcoming Tristan, and how he had suffered from jaundice, and had tongue, cheek and lip ties, which causes difficulty latching during breastfeeding.

"Breastfeeding, for me, is definitely harder than I thought," she said in Feb.15 update while cuddling Tristan in front of the base of her bed. "Hard, but very gratifying. I love it."

"I'm sure that I've been having the same journeys that you all went through," she continued, "so I want to tell you guys my journeys and my strengths with everything, some of the challenges I've been having."

"I love it. I love skin-to-skin. I love breastfeeding," Heather added, saying that "luckily," she has been "producing a lot of milk," but overall, "it was harder than expected."

"We're now 2 weeks past getting his tongue tie fixed and he's latching so well on the left side and we're still working on the right side using non-traditional positions which were shown to me by the baby fairies 🧚‍♀️," she said of her experience, noting that a mother's "nutrition and hydration" are important while breastfeeding as "there's not much time to take care of yourself."

"Even with all this going on, I genuinely love breastfeeding," she added. "I love the skin to skin connection and think it's such a beautiful bonding experience. It might be hard and challenging at the moment but it is such a special experience that I get to share with our baby boy and we're working together to make it easier like we're a little team 🤍🍼."
