Thinking of having a second but worried about sleep…

Katie 🇬🇧

So me and husband are thinking about having a second baby. Our son is 3 in May and he’s an amazing sleeper. Has slept through from around 4 months and sleeps 7-7:30 every night. We have the odd night of bad sleep if he’s not feeling well etc. But we’re so worried about a 2nd not sleeping well. Everyone says to me ‘ohh but if you have a 2nd they’ll be a terrible sleeper’. Can someone please reassure me that this won’t be the case for sure, or has anyone got two children who both sleep really well???? Thank you!!!
