Constipated baby at 6 months

Nagstart si baby kumain ng solids last week. Ebf siya and everyday ang poop niya, at least twice a day. Pero last niya nagpoop nung 11am ng Sunday pa. Di pa siya nagpoop since then although she farts after feeding. Is this normal? Pedia said bulkier na yung poop. Any moms na naka-experience nito with their babies?
