Struggling with feeding

My friend had this issue and it was due to severe tongue ties, high palate and feeding issues. Bec of this, baby wasn't able to latch, once sorted, baby was on bottle only.

I’m having this issue. My little girl is 7 weeks and it’s been like this since 4 weeks. After an oz or 2 she’s screaming and wants more but is just guzzling and screaming. It’s making feeding so stressful. She’s formula fed so only has the bottle but no matter what we try she won’t drink properly. She also always has belly ache as she guzzles so much air when drinking as she’s so worked up

I had this issue around week 5/6. Basically my LO latch wasn't as good as it had been where her face/lips had changed shape. She was no longer pouting out her bottom lip and was getting frustrated. The same thing of managing better when tired.
All it took for us was to pull out her lip so the were flared around instead of tucked in and she could feed more effectively. Did this a couple times for her and she wuickly caught on with what to do

We had this with my first son but worse. I remember it started gradually at 7 weeks. Also weirdly fed ok when asleep but he also didn’t feed as much asleep as slept well in the night. He was super uncomfortable after the feeds too and upset. He then stopped gaining weight and we were put on omreprezol and a hypoallergenic formula. Possibly it was that or he just grew older but it went at 3 months. He turned out to be the happiest baby/ toddler who loved food , but so stressful at the time!

When my little girl pulls off I find it's from gas so we have to have breaks and a good posture for feeding to help her feed.

We had feeding issues from day 1 and at 7 weeks someone finally identified tongue tie - we had similar issues where she would pull off and get grouchy because she was so hungry - also caused some bad gas and reflux for us. Apparently it can only get identified in some babies around 6-7 weeks as their appetite increases and they can’t get what they need. I would get that checked out as it’s made a huge difference after only a couple of days. It’s a super straightforward procedure.
