My 7 month old sleeps right through, My 17 month old has just started sleeping through the night after spending about 5/6 months in bed with me and my partner, all I can say is just hang in there. It doesn't last forever and when your little one does sleep through the night in their cot you'll be lost 😂
My LG is 18 weeks and sleeps soundly from 10pm - 4/5/6am, feeds & then I try to put her back in next to me & she just stirs so I put her In Our bed & she sleeps 😳 but then I don’t really 😂 Sorry no advice but I’m in same boat x
