Does anyone know if physically breastfeeding can make you tired? I am exhusted at the moment. Especially during the day which is when I am feeding 2 hourly. I am literally falling asleep anywhere. My toddler woke me up today, cause I had fallen asleep just sitting on the couch holding my baby. I realise having a 4 month old and a 2.5 year old is tiring but this seems extreme. I am taking breastfeeding vitamins + a super B for energy but it doesn't seem to be helping. Has anyone else had this? Is there any vitiamins that could help?
