Just needed to rant!!

Hi all. My baby is turning 6 mo in a few days time. I worked very hard for her to have the routine of eat, play, sleep. Usually her nap time is 2-3 hourly, wake time ranging from 1-3 hourly. Mornings will include 1 milk feed (9-10am) and she will wake up at around 12ish or 1 pm. (I can usually do my laundry and washing during this time) Her next nap will usually be around 3pm - 5pm, shower then by 9pm she will be sleepy. So past few days I went for a family gathering and they kept playing and letting her watch tv nonstop. Ever since then, she refused to nap. Even if she does, it’s a short 10-15 mins nap before she’s awake for 4-5 hours. She sleeps around 11pm - 12 ish now!!! Im going over again (celebration) and I’m really really annoyed by my grandma telling me baby is not sleeping because she misses her and I should give her more tv so that she will be tired despite me telling her baby’s schedule is screwed up after spending 1 day there 😠 She even asked if I can go over earlier so she can play with her more. I know she meant well but I just cannot. You can spend less than 24 hours to screw up a routine that I tried so hard to maintain for months!!!! It’s very exhausting for me as I’m the only caregiver at home. With her current screwed up naps, I can’t do anything. I am very very annoyed 😭 I totally understand that they tends to sleep lesser as they grow, but this is a routine she has been sticking for months and it’s just so coincidental that the entire routine got disrupted after 1 day of visiting. I could tell she’s very tired with all the eye rubs and screaming/crying but she just doesn’t want to sleep😓 Thanks for hearing me out. #1stimemom
