I was just wondering what I should pack in the bag for Mia, her dad is taking her out for the day on their own on Sunday (normally I go but leaving them too it now she’s old enough)... I’ve got her nappy stuff & change of clothes ... I’ll pack her food and drinks on the day... is there anything else I should pack? 😅 normally that’s all I’d take really so I’m hoping that’s fine... 😆 think I’m panicking ! Letting my baby go gonna be horrible day for me 😖😖
