Advice for weaning at night

Reem

Hey everyone! My son is 18 months and has only breastfed. He wouldn’t accept formula at 9 months and even trying to give him whole milk after he turned 1 he would take a sip or 2 and be done. I have started weaning and he would feed when taking a nap in the afternoon and at night. So far I rock him to sleep in the afternoon and he’s fine, but at night time i walk and rock him and he stays crying. What has helped you especially during night time? He sometimes wakes up every couple hours or 3 times. Any advice is appreciated!! Thanks
