yes , that's normal...every phrase is different. for my gal cause she is having her teething that time so is cranky and will always wake up in middle of night..its kind of different stages. my gal takes quite a while to go bk to her sleeping throughout the night. they will react differently in stages for different baby so it depends
I think is normal. U may try to increase intake 😊 a sign of hunger and I think once he start solid food it will help him sleep through the night :)
