Any other moms with 4 month old have an issue with their LO not fully holding head up? My LO wants to constantly look up and arch his back. If I sit him up against me on my lap he does really good but other than that lets his head go back. He absolutely hates tummy time and screams the whole time and will arch his back and balance on his tummy like a seal. I've been trying not to read milestones because I worry he is under developed but know every baby is different.
