Crikey some of the posts here are so judgemental - unless you are a single mum to triplets I don’t think you can really judge her for doing what she needs to do to survive. I’m a new mum myself & Christ it is hard and i only have one & he has always been a relatively good sleeper. Yes she probably knows that sleepyheads aren’t advised for sleep but loads of people use them/endorse them & unless you have been in her position I don’t think you can judge. As for her having a night out & you haven’t then more fool you - my baby is 9 months & ive been out 3 times with my friends since he was born. It meant I got a break, a chance to recharge & just be me again & is essential self care to be a good mum to my little boy if im honest!
