my dd is 4 months old, currently she is having 7oz at 7am, 11am, 3pm, 6.30pm and then she may go through till 7am. On the cow and gate box its says she should be having 5 feeds in 24 hours. Should I introduce another feed during the day. I think she may be hungry as for the last 2 nights she has woke around midnight for a feed.
