Its called the witching hour. They can be fussy/unsettled for no reason, i find sometimes giving more food can help at this time. I have wheeled my little one in the pram in the house to settle. Gotta trial and error but its called the witching hour 🥹
My little girl does this and she is 2 months and 1 week old but some days she is like it during the day as well as evening time until 10pm or 11pm then she will sleep but in-between she is on and of crying when I know she is tired it's hard to try and settle her to sleep then when I do a few minutes later she is crying again
Mine is 5 weeks old and does exactly this. Is so chilled through the day but so restless in the evening. No advice just trying to get through it lol I save activities for the evening, have a bubble lamp, some sensory toys, put him in his chair with music, have a bath etc and keep switching it up. So hard when they aren’t settled though for sure but you’re definitely not alone
