Exclusively breastfed baby trying to wean

Taneesha

So my son just turned 1 years old 2 weeks ago and Iv been trying to slowly wean him off the boob and to get him drinking milk from a sippy cup. Problem is he’s been exclusively breastfed so if he drinks from a sippy cup it’s literally the tiniest amount and he pushes it away and it forces me to breastfeed him so he gets fluids instead of weaning him. 😩 need tips need help need anything lmao
