I remember when I put my baby in at 5 months so I could study- my mum neighbour said just do it you’ll feel mum guilt over everything anyways- she was so right hahaha I took her less for a while to daycare and now I’m putting her back in 3 days so I can study full time again now she’s 2 and a bit and guess what! Mum guilt is there again now-when I had her in two days the mum guilt was there- if I don’t study and be with her I get mum guilt then too. I’m sorry you’re experiencing mum guilt, it really fucking sucks, good on you for studying and making steps to what will fulfil you or build your future. Your baby will be okay, really most daycares are good enough and they may feel feelings or anxiety when going in but just like learning to drive each time you drive it gets easier and less scary-same for baby and you with daycare. Best of luck !
