I feel pretty similar at times. He has been really smiley and engaging with other people but for me recently he hasn’t! When we’re together alone at home I start worrying about his development and why he’s not making eye contact or trying to engage with me but then I see him do it with other people and I think maybe it’s just me then!
You and your baby are 100% as connected as ever and you still have that bond! You are your babies whole world❤️ You spend the most time with your baby I’m assuming? They could be making eye contact with other people because they don’t see them as much and are sussing them out? Babies smile when they are amused so it could just be different faces are amusing them!
Agree with what everyone else has said. You are your baby's safe space and I really feel like some days they are just quietly processing all the new learning and experiences, which is probably why they're less engaged some of the time. I sometimes feel the same as you, but try to remember that even as adults the people we're able to sit comfortably in silence with tend to be the people who we're closest to 🥰
I know it’s easily said than done but don’t overthink it, my little boy is 4 months and he’s not ALWAYS smiley or chatty with me, remember he’s with you all the time, and other family members/friends come and go, don’t worry about it because he might be able to feel your worry! 💖
