Fighting when eating

Cassandra 💕

Baby girl is 15 wks & the last week or so there’s times where it’s been such a challenge to get her to drink her milk. She’s formula feed. She wiggles, squirms, fusses, and just fights me and always try’s to sit up. I thought maybe her nipple is to slow and she’s working to hard so she acts crazy. But switched it to a 2 (3-6 mnth) and she still acts the same.

She’s been drooling like crazy and hands are constantly in her mouth, I know she’s teething as I can see her gums raised on the bottom.

She’s only been getting about 25 oz a day instead of her 30-32oz. Is this a phase, should I consult with her Pediatrician?
