Help choosing gifts for new parents... (BIL and GF)

Myself and my husband welcomed our 1st born back in July. My BIL and his gf got our son a sleepsuit as a gift (not even wrapped, I might add 🤣🙈).

They’ve just had their baby boy this morning but I’m struggling on what to give them (I’ve bought little bits since I found out they were expecting - some for now and some for Xmas stocking fillers). I was thinking the pack of sleepsuits and Moses basket sheets as they’re probably the most useful but is that enough? Should I include some of the other bits? If so, what? I’ve obviously got them a card too. Honest opinions please!!
