Is my husband neglectful? How concerned should I be?

I’m a sahm and do all our baby’s hygiene care, sleep feeds, doctor’s appointments (due to health issues), spend the day with her and put her to bed. After work, my husband takes her for 4 hours so I can shower, organize my pumped milk from the day and nap (I’m up 4-5 hours for baby in the night so the nap balances it out). She sleeps for 1.5 hours of this time. Whenever I get up to pee, pump or put her to bed, he’s on his phone, watching YouTube or talking to his brother (2-3 nights a week). We have constantly been fighting over this as he compares it to my EP for our daughter (latching issues) since I don’t give her my full attention while I pump. I pump for 1.5 hours a day with her and her pediatrician wants me to continue this as long as my mental health can handle it. I agreed we won’t comment on each others parenting a few nights ago cause I thought the arguing was bad for our daughter and felt my parenting balanced out his. However, he escalated further yesterday to the point where I feel like he’s neglecting her? I came out last night around her bedtime and she was crying, alone in the living room and laying on her face. Husband was in the kitchen talking to his brother. He claims it’s healthy for her to have tummy time, her crying isn’t a big deal and he was checking in on her. I do tummy time too, but I’m with her and try to keep it a positive experience for her(hellium balloons on her hands to keep her occupied, water toys in a tray of water and her propped up to play with them, playing songs on her light up key board with me as I make up lyrics, etc). She can’t roll onto her back yet so she’s entirely dependent on us to help her when she can’t keep her face up any more.
