My 5 month old boy has never been a good sleeper, however at 4 months sleep regression hit and he's been waking up every 2 hours for the past 6 weeks to feed (breastfeeding). During the day he feeds every 3 to 4 hours. Is there anything I can do to extend his feeding time during the night? I'm so sleep deprived!! Is it perhaps time to start weaning him?
