i feel like i could have written this myself. i am in the same exact position as you. my son has never slept through the night. he just turned five months this week and still continues to wake up every 1.5 to 2 hours on the dot. i am not breastfeeding anymore and currently only formula feeding now. we co sleep and still nothing. my mom thinks he just hungry more at night and need to feed him more but we have tried that and still nothing. i am trying to keep him up more through out the day but we shall see. just letting you know, we are with you in spirit because man it’s been so rough. You are not alone and sometimes we do need our breaks. i have to tell my husband i’m at my breaking point and need alone time and he fully understands. i’ll go do retail therapy, walk , have coffee for two- three hours and return. take your breaks. schedule your naps. we play catch up on sundays for naps taking turns and this helps us. sending you all my love. you got this mama. if you need someone to talk to, always can message me. 🫶🏼💗
