So Our DD was doing brilliantly and sleeping from 9pm-6am from around 3-4 months old but in the last month she wakes every 2-3 hours wanting fed. Shes gone from 7oz of formula per feed during the day to only ever stretching to 2-5/3oz but will have 2-3 7oz bottles over night. She is teething and has 2 erupted and 2 just under the gum. I was wondering if anyone else experienced this and how long it lasted for?
