Hi all hope someone out there can help me i am breast feeding my 4 month old i been having a lot of problems with my milk the past few weeks and have been having to give him 1 bottle of formula at night as i have had no milk at all in my boobs for him. anyway moving forward to about 4 days ago and i have been having to give him a bottle in the morning too.. hes waking up more than he use to during the night feeding i been taking fenegreek but that is doing nothing what so ever and cant get into the docs till tuesday next week to get help from them... Today he has refused the boob all together he will suck pull off suck pull off and scream there is milk in them but he screamed till i gave him a bottle... i really dont want to give up breast feeding but it looks like i have no choice he just wont take the boob at all now. I just feel like a complete failure i really wanted to get to 6 months but im no where near that i just feel completely shattered as i loved feeding him :(
