rant.. babies sleep

Last night was hell on earth in our house. Baby woke at 2:30 (her usual), nursed her and she fell back asleep, I changed her diaper and BOOM, wide awake. For 2.5 hours!!!!!!!! 😩😩😩😩 Then I felt like a terrible mother bc I was getting mad at her ☹️ I was just so tired. I tried to let her cry it out (she's almost 7 months old) but my husband couldn't handle it. She literally stops crying as soon as she sees me stand up out of bed and starts kicking her legs and smiling.. Separation anxiety? I pray to god this doesn't happen again tonight. I feel so bad with how frustrated I got. She just wanted her mommy and to play..
