hi, my DD is 3 months old, breastfeeding and sleeps for a 7-8 hours a night. in the morning her fontinalle is slightly depressed and pulsates, her nappies are always nice and wet and the depression gets better throughout the day, although doesn't always disappear completely, is this normal or should i be worried shes becoming dehydrated? I am completely obsessed/worried with the fact i may not be feeding her efficiently enough!!
