Also you can't rely on sleeping when the baby sleeps. Some babies don't nap well either! (Mine naps for half an hour at a time at the minute - no matter what!) some only sleep while being held too...
DD1 was like this. Fed for nearly an hour, napped in my arms then screamed until the next feed. If I managed to get her into the moses basket/pram, I was lucky to get half an hour and, as I said previously, I'd rush around doing jobs. My MIL was wonderful - she'd take DD out and push her around the streets to give me a bit of respite. I did a lot of dozing off whilst feeding.
At 3 months, we were lent a wind up swinging chair, which also gave me a bit of respite. They were fairly thing so needed winding every few minutes - I imagine that, after 20 years, they are much better now - but at least it was a break from the constant crying.
You just learn coping mechanisms and do whatever it takes to get through.
At one point I was so tired that I woke up one morning and genuinely thought I'd put the baby inside our duvet cover - I was scrambling to open the poppers to get him out
Me too, been there, got that t-shirt. 🤣🤣🤣🤣🤣
At 3 months, we were on holiday and I hurt my back. At night DH would bring DD to me and I'd feed lying down. He'd take her and do the nappy and try and settle her. I realised this made a huge difference as I didn't wake up fully and wasn't awake so long. This became our weekend routine. I also fed her in bed with her tucked up on the moses basket mattress. If I was lucky, I could then lift her back into the basket without her noticing. You find ways to cope.
