number of pees

Da
My baby used to pee 8-10 a day when she was waking every 2 hours at night. For the past two days she's only had 6-7 pees when she's been sleeping 3-4 hour stretches at night. Should it be changing? It's now 10 am and I've changed her diaper twice but she's only had 1 per since midnight... Getting worried
