Baby has become a nightmare at night! 😩

My 15 month old was previously doing her only nap at midday, but she’d only sleep for 30-45 mins. Lately she’s not seemed tired at midday so I’ve been putting her down to sleep about 1pm and I’ve found she actually sleeps about 1.5 hours, which is great! We’ve pushed bedtime back by 30-60 mins at night because she was refusing to go to sleep any earlier. Now she’s going down relatively easily, and maybe even sleeps well for the first half of the night (its 50/50 at this stage) but then the second half of the night is HORRIBLE. We’re up and down constantly. She’ll go back off to sleep and then like ten minutes later she’s crying again!!

Is anybody else going through this? She used to sleep so soundly through the night. I’m sure it’s just adjustment to the new nap routine, but it’s killing me and especially my husband, I worry about him going to work and operating heavy machinery on such little sleep 😩
