Help, tired momma of 2.

Cortney

My 5 almost 6 month old still wakes up every couple hours at night and his naps are only about 20 minutes during the day unless we are in the car. He gets fed purées for breakfast and dinner plus he is breastfed. He takes a pacifier and sometimes that satisfies him, but mostly he has to nurse. My daughter didn’t sleep through the night at this stage either but I feel like we got more than 2 hours at a time and her naps were decent. Does anyone have any tips to help him sleep longer? Has anyone used the weighted sleep sacks and had success?
