Pigeon slim neck to wide neck

Honestly, a few of us tried switching around that time din and our babies adjusted pretty quickly, hindi sila naging confused because the nipple flow is what matters most to them, not really the bottle shape itself! I'd say go ahead with the Wide neck if you prefer it (mas convenient talaga pang bili ng extras), just observe lang if your Lo has any feeding issues or gas, pero in my experience walang problema. If the Slim neck bottles are still okay naman gamitin, you can keep using them too habang nag-adjust siya, hindi required mag-switch all at once, pwede mo i-mix and match nang walang guilt!
